A while back I bought this hub.
http://www.amazon.com/ULTRA-PRODUCTS-ULT31808-Buddy-Hub/dp/B000A3JDBE
What made me pick it up is that each individual port is switchable between two computers. I use it to swap my keyboard, mouse, and flash drives between a desktop and laptop. Just tried it out with the Xoom (Rooted Tiamat 3.2) and a usb keyboard, mouse, and a flash drive all worked without a problem.
nice, it'd be nice if the xoom docks had working usb ports...

True. I ordered a dock that should be here tomorrow of Saturday. First order of business is to open it up and find out how they wired it. Since it does plug into the usb port on the Xoom I can't imagine it'd be that hard to rewire it to a regular usb port.
.....Assuming I don't destroy the dock trying to open it.
I found some pics on another forum where someone opened up the standard dock and added a USB and HDMI port to it (by basically just running extender cables). It looks like the dock is really just a USB sound card. I have a USB sound card I got for 25 cents that I used in a project to turn a cheap router into an internet radio. I'll have to try plugging it into the Xoom and see if I get sound out of it.
I have been trying to use some flash drives as external storage however I ran into some trouble.
1. First of all without rooting and getting a kernel or something (which I cannot do as my phone is sim and bootloader locked to o2 right now) it can only read FAT32 formatted drives rather than NTFS.
This means I have to either split >4gb files into two smaller pieces or re-encode. I don't like re-encoding because of the great hdmi output so why not carry full blu-ray rips
2. Does anybody know the power output of the USB port in the Xperia S? Is it something like 100ma or less? As you can see from my photos below here are my tests,
Sony 16gb Micro Vault Click USM-L (pink)...........works fine.
Sony 16gb Micro Vault Click USM-P (black)...........works fine.
Verbatim Stor N Go 32GB Micro USB (tiny one)..........USB Power Consumption Error
I don't like the fact that it is hit and miss when choosing drives and don't always want to carry around a powered USB hub or a Sony Ericsson Livedock instead of the tiny drives and the lightweight micro usb->female usb cable.
Its meant to be "USB On-the-go" not "USB can't go because my arms are tired and bag is full"
There is NO information on either Sony's nor Verbatim's website regarding the power consumption of their flash drives.
Any suggestion's?

did you try to conncet wireless keyboard ?
did you buy any in particular ?
i have already order this one
http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=320739400862&ssPageName=ADME:L:OU:GB:1123
i hope will work. will it?
hi i also bought a cheapy one from ebay and its perfectly fine
yes usb keyboard and mouse works fine, tried logitech k800 with unifying receiver and also tried microsoft keyboard and mouse desktop combo with big ass usb receiver. i have not tried bluetooth yet but that would be preferable to me because it will take one less port.
i would also like to hear about the livedock or if anyone has made a a simple y cable with "micro usb male" (to go into phone) split into "female usb" (for usb device) and "female microusb" (for charging input).
In fact why not go the whole kaboodle
A. Keyboard & Mouse & Headset & Phonejoy controller & Smartwatch : simultaneous Bluetooth
B. Flash Drive or USB Hub with multiple drives: Micro USB to USB adapter
C. TVOUT : HDMI
D. Charging : Female Micro USB input from same spliiter cable as B
now its a full desktop, NES, SNES, whatever all controlled by any of the above and the damn thing is the size of your hand
View attachment 962244
Basically does something like this exist?
This cable should in theory have the same functionality of the bulky livedock?
I was thinkink about same thing: y cable, so we were able to access flash drive (memory card) along with charging the phone. But i think it is not possible with JUST a cable. I think it is possible with live dock, but live dock probably got some sort of electronic curcuit board which controls flash drive and charging at the same time. Unless you would buy live dock for other phone (P in example), take curcuit board out and do DIY.

That all sounds really cool to experiment with, but thats alot of gear to cart around... wouldn't it be easier just to buy say a PSP(homebrew) or perhaps a PSvita? Emulation is wasted on a touch screen.
The kernel mods in the dev section have already enabled ntfs fs reading amongst other things, you could flash these right now or the first roms will probably have this soon which should help you out quite a bit.
I bought the livedock for the XPS hoping it would work for usb charging via computer, it does not; a Y cable is a good idea tho... unfortunately the dock just does not suit the XPS at all, does not sit correctly, u have to lean the dock usb connector on the ground for the whole setup to be "somewhat" stable and just looks silly, not to mention unsafe.
Those clove youtube vids area bit of a con imo.

Does anybody know where we can buy the original Sony Ericsson USB OTG? Also, does anyone know the part number? I do not want to use any other brands. Hope someone could help
Any reason why? You can buy it of ebay for just a couple of pounds and is working fine.
I connected Logitech RumblePad to my xperia S (Using some samsung USB adapter)- including vibrations, so i think power output is pretty ok.

hi it wouldn't be too much to carry around, consider having a phone and a vita and a laptop? at what cost. you'll still always need at least 2 devices, you phone and another. now you can have all three from one nice looking device and can take each accessory when required. ie all three to a hotel, just the keyboard for working on, just the gamepad when you feel like it. check out the freedom pro keyboard (better than a laptop's) or the phonejoy for a full vita beating experience (comfort wise - wireless on big screen anywhere)
and minimising what we need to carry is the whole point of finding if such a y cable works because then we don't have the added bulk of the Livedock...
thanks for your review of the livedock, even more reason to want that cable! I cant believe there is no grip, i wouldn't have been able to assume that from the Clove videos. its a bit silly that the Xperia P has the new smartdock but because they put our ports on opposite sides we can't use it
i noticed the devs have a kernel for ntfs compatibility but i cant use it as i havent even received my sim unlock code from my network let alone finding out if my locked bootloader can be unlocked after this. plus ive just discovered how bad the yellow tint issue is on my phone, so its a bit of a wait for me!

yeah but i don't think the wireless receiver for the rumblepad takes up as much power as constant reading from and powering a flash drive would. the wireless receiver doesn't need much compared to that and the controller itself has its own battery
nevertheless you could be right in suggesting that the power output is ok as it powers some but not all drives, so if its not power output then there is some other reason for the compatibility issue with each usb device... so we should do a list of what drives work and which dont
Hi
just want to know if this will work with the Xperia S

I asked the seller but he says its only compatiable with nokia as it a nokia branded cable but surle all these cable are the same as any generic ones as they use the same connections?

it looks like this cable will work perfectly fine, just branded and looks pretty nice actually. however id be weary of choosing this when there are right angled micro usbs on some adapters...these are more practical in my opinion after having used my similarly priced generic ebay otg cable and also the standard charger cable that comes with the phone

wow confirms the plenty of power theory then, does it rumble and everything all powered by the phone?
Understood.
Yeah i'm a huge fan of mobile docks, they screwed us over regarding that i reckon, bad bad port locations...
Sorry to hear about your yellow tint issue, what a pain in the arse, reminds me like some kind of sun damage i've seen on other devices before left on the car dash for an hr.

Yes it does, i had to connect it 2 times, at first phone said it takes too much power, but on 2nd time, it worked fine, and yes it did rumble when i pressed vibration button on it ;-)

I know the right angled ones will be better, but i just love the build quilty of the Nokia one so will probably give it a try.
To anyone interested in OTG cables:
Guys, the Nokia OTG cable works just fine and is VERY good quality and very common anywhere (quite cheap as well).
Tested by me. Already connected my 16GB Ultra Speed Transcend USB drive and works fine.
I've been using OTG since day 1 when i got the unit - like the OP says, the power consumption of the USB port for devices are hit-and-miss.
Some usb drives works great, some consumes too much power and cannot be powered on; so far, my wireless keyboard+touchpad set (rapoo) works great.
In the last few days dad got an Archos 80 G9 Tubo - yes, i helped him pick it out . i also spent a couple days with it playing with it and setting it up.
One of the things she wants to do is plug in a USB stick, but the port on the back is almost unusable for anything because its so close to the silver plate inside - there's simply not enough clearance. The one cable he was able to push into it (the cable from his iPod classic) bent the port at such an angle i was worried it was going to break.
WITHOUT ROOTING (i tried rooting his X2, that went over like a ton of bricks) is there a way to use either a USB on the go cable, or a super-slim USB extension cord (if it exists) to make a full sized USB port available to him?
Thanks in advance for any answers.
Hello,
There are 3 ways that I'm able to attach a full-size USB flash-drive stick into my Archos 80 G9 Classic:
(1) using the micro-USB port with this USB-female-to-micro-USB-male adapter works for me when I want to attach any "fat" full-size USB stick (search for product #B006XL26TS on Amazon);
(2) using the full-size-USB port without an adapter - this thin USB flash drive can attach to that weird angle full-size USB port with ease without using any adapter (search for product #B003DTLWHU on Amazon);
(3) using the full-size-USB port with a corded adapter that looks like this but not exactly this particular model (search for product #B001TH7GV4 on Amazon) - I don't remember where I got this adapter but it fits fine in that full-size USB port and I can attach any "fat" full-size USB stick...
Sorry I couldn't post the direct links since I don't have enough posts. Good luck.
thanks a lot.
i was thinking something like #3, i'd love to find a super-slim extension cable.
i use an ordinary usb cable i made fit using a cutter knife. this works quite well.
I use a stripped usb stick, by removing the casing from the stick.

The slots are the same, but if they give the same amount of current i don't know.
I I know from my 80 that a old school mouse worked, but the mouse what i have now doesnt.
ok tried these
2 usb thumb drives both worked
logitech mx 518 mouse didnt work
USB Key Board didnt work
Tried both thumbdrives with a 4 port hub and didn't work. expected that, now I need to find a battery powered usb hub anyone recommend one
I did some googlefu looking for battery powered USB hubs and found a bunch of them but most are for charging I was looking for one with data also. then I found THIS the hub hes useing is the same as one I already have I have a dead coby tablet that has a 5v battery in it that I can use. just a thought has anyone used a external battery to charge their tab and do you get slow charge or fast?
with all the coverage the motorola laptop has been getting these days (google: motorola lapdock rikomagic or motorla lapdock raspberry pi )
I got one to toy around with it my self. I'd really like it to work with MHL devices. Thats the moment I found out that MHL's micro usb in is to charge the device and get the HDMI out to work, but doesn't pass though and more usb data though. I imagine the bandwidth is too great.
So as a consolation I thought it would be cool if the lapdock's mouse and keyboard were bluetooth, then i could connect to its display with hdmi, and control the phone with the bluetooth input.
Does anyone know if there is a generic usb device that allows you to connect a USB keyboard and mouse and then transmits though bluetooth? alternatively does any one know of any relevant mods that might help me hack this together?
The problem with MHL is that it uses the electrical path from the USB connection.
The problem is not bandwidth, it's wires.
All of the funny things that plug into a micro USB connector just use the same 5 pins that are already there and repurpose them.
This includes "Carkit", which is the analog headset/ handsfree connection or MHL.
usb flash is also possible to connect and then not get what you
If you wanted to be really hard-core you could add another micro USB connector to your phone.
You'd have to pick off the USB signals as they come out of the PHY interface and before the main connector multiplexer.
Or you could get the guts out of a trashed BT keyboard and wire it to your Lapdock keyboard.
You wouldn't have to get the layout correct, you could just fix /system/usr/keylayout.

I looked and haven't found one. However, during the search I found the KBtalKing Pro mechanical keyboard that solved my problem (well, when it is officially released next month)--it will allow me to use it as my main desktop keyboard (which should be great to type on due to the use of mechanical keys), and also pairs up to 10 devices via Bluetooth as well as one main USB device (probably the main computer). Looks like I'd be able to type on my Android, iPhone 4, PC or Mac simply by pressing a couple of buttons on the keyboard to switch over.
Probably not the economical USB to BT conversion you were looking for, but it's a solution and then some.
You can check out handheldsci com/kb it looks like what you want.
Hi,
Did someone try up this handheldsci adapter ?? It looks indeed as the solution to use any input device/combo without using the usb connection (very useful for smartphones).
***EDIT***
USB Host DOES work with Flash Drives. For information see post 3: http://forum.xda-developers.com/showthread.php?p=37201971#post37201971
This is now my main focus. So I figure why not everyone post up what devices they got to work with the Kindle Fire 2 and/or what methods it took for you to do so.
3x Different Flash Drives: Not Working However one of their LED's Illuminate
USB Keyboard: Not Working
Logitech M570 Wireless Trackball: Working
I also tried a non powered hub, it didn't work. The Green LED Illuminated but nothing more. When connected to my Galaxy S 3 I can have multiple devices attached at a time. I tore the Hub down and found that it has a blank slot for power. I wired soldered in a 0.75a Samsung Wired Charger to it. It Illuminated the LED, As well as it illuminated the Power LED in Orange on the Kindle but no devices worked on the Hub. I tested the power output of the USB Ports and it was a little more than 5v per port.
Device: Kindle Fire 2
Rooted and TWRP'ed with the Nightly of CM10.1 1-20-2013
Will keep trying. As stated in another thread, that its simply power. After testing these things out, I don't think its power related. Either the kindle just doesn't have the "Drivers" if thats what you'd call it, or it simply can not run anything but a mouse. I hope that is not the case. It will ruin all appeal in my eyes.
If you're rooted, have you tried installing StickMount?
Might work for the flash drives.
I tried, Stickmount tries. You can tell its trying to work something out. So more tests with a cut up usb cable on the OTG cable does in fact show there is a voltage issue. My Galaxy puts out perfect 5v. The Kindle puts out around 2.5v. I tried making another OTG cable but failed. I guess its just not getting connection to the extra pin. So I have a USB Extension I'm gonna split open and power it. So I don't have to hack up my only working OTG.
The main issue I'm having with this is, my current power unit is a measly 0.75a. And It charges the device. So I figure there will still be a voltage issue due to the device charging. So I could cut the red wire going to the device for now. But not sure if the device will realize this somehow and just not work. Thoughts? I've seen this done before when someone made themselves a powered OTG Hub system out of a couple USB Cables.
I'll continue till I'm too tired to think hehe.
***Edit***
Ok couple hours later.... lol I had a USB Extension, I cleanly just slit it down the m iddle and soldered in the two power wires from a samsung micro usb charger. The Power is 5v at 0.75a. So its not much. I know it wouldn't charge my nexus nor Galaxy Tab, but it charges the Kindle, or at least the kindle says it is. I doubt it really is. Anyway I soldered it in, cleaned up the surgery started some testing on my phone first. I connected a Micro USB cable to one end and then the other to my phone, and then the Kindle. It charges, or again says it is (*kindle might require more amperage). So Next I connect the OTG Cable to the other end and connect it to my phone, It charges through the OTG Cable. Next the Kindle, it does not charge the kindle. Possible amperage requirements, I don't know yet.
So onto the test without StickMount, Failure. It acts the same.
Test with StickMount, Well I'll let this screen shot explain most of it:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
It worked! StickMount notification pops up and I found the flash drive in the current location. Inside the SD Card under a folder called /usbstorage/sda1/. Not exactly my first choice, not sure if this can be changed to go into mnt or somewhere else. The Device itself doesn't notice the flash drive. So if you go into System/Storage, it does not show the flash drive. But it is fully functional. I accessed some files without any issues.
So my final consensus: The Kindle Fire 2 currently has OTG/USB Host Capabilities. From the USB Host Diagnostics I ran, its fully functional. However the main issue is Power. The second issue is the device on the most current (1/20/2013 CM10.1 Nightly) rom doesn't have the proper... I don't know the right wording for it, but lets say drivers since I'm a pc guy. I'm sure with more development, it can control any device with the only issue being power related. This takes away from the meaning of "On The Go". Having some sort of 5v power source connected to your device while your trying to use a hard drive or something else is going to be a pain in the ass for most people. For me it really does not matter since the device is going to be setup in my car for media sourcing as well as game play. So a 32gb flash drive and a Xbox 360 controller is all I will be using.
I will be doing more testing with multiple devices but it is 4am right now. One more thing, Bluetooth abilities are possible with a cheap dongle. However for some reason the Kindle recognizes it as a physical keyboard. I have tested this on other devices in the past so I believe it is possible with some more development. But that's far in the future and still of course require additional power.
Goodnight guys.
I have 3 different thumb drives.
Sony 4GB = does not work
SanDisk cruzer slide 16GB = does not work
SanDisk cruzer 8GB = Works
The regular cruzer is probably 5+ years old. I have access to others and will update my post when I get them.
I'm on PowerPoint45 cm 10.1 using chainfires stickmount.

Nice. The regular flash prob requires less power. I noticed one of mine which was larger almost worked. But would shut off prob to not enough power. But a newer one wouldn't light up at all.
Plans for today: To re build that USB Hub I was messing with last night. I desoldered the USB cable off of it to solder in a Micro USB, But I don't remember if it worked. I then tried to turn it into an OTG direct 4port hub but nothing happened. So I'm sure I screwed something up. But the initial results should be a powered, 4port Micro USB OTG Hub. I just hope I have enough juice to make it work for not only charging the Kindle but powering the devices on the hub. I have a Galaxy Tab Official 2.0a car charger I can try out. I want to be able to have at the least, a 32gb Flash Drive and a 360 Gaming Controller.
Well I got some done today. I found an old phone charger that was 1a. I finally just used my OTG Cable and soldered it in place of the std usb connector on a cheap USB Hub. I'm sure everyone has the same hub I'm using, I have two, one says Microsoft on it, the other says AMD but they are super cheap and are given out everywhere you go:
Its a non powered USB hub, however when opened up there is a bare spot for a power connector. Middle pin is 5v + and the two around it are common Ground -.
Don't be strayed by my crap solder work. I'm using a cheap harbor freight soldering iron and the new charger has very thick wire so it didn't really fit in the small holes. The ground is just directly connected to everything else thats ground related so I grounded it there. That way the two wires aren't soo close together.
I have now successfully tested 3 flash drives, NTFS, Fat32 and some strange Fat32 drive plus my Trackball. As well as this I have successfully charged my Galaxy SIII off of the hub. I wouldn't exactly recommend this unless your running like a legit 2a charger. I only did it to test out power requirements. I think either my cable is damaged too or I'm at the limit of power the small 1a can handle because every once in a while the hub shuts off. I think its just cable related.
Here is everything connected as you can see.
However the tablet it self is not charging. At least the icon on the notification bar doesn't say so. I have tested the voltage here and its 5v. But IDK? Maybe the Kindle wont allow it? BUT, with all my testing, the battery has stayed at 88%. I'm gonna try to kill it some more. Maybe with some transferring files between drives.
lol As I'm typing this, I sit down for a second with the tablet on the carpet floor and just stare at it. I've noticed that some reason the led turns off and on at random times. But I've never seen it say its charging. Well the screen just dimmed but didn't shut off so I get up to check real fast and when I turn it on, it says 88% - Charging! But then instantly goes back to 88% - Not Charging when the screen lights up. And there it goes again (Please bare with me as I'm doing this all this very second.) Looks like it just needs some more amperage. 1a is not enough to power everything and charge the device.
I was worried that the kindle wasn't going to support Charging OTG. Well I happen to have a spare 2a Galaxy Tablet charger and no Galaxy Tab.... I'll try it out and get back to you guys!

This looks good! If you want, once you are done with the testing, I can try and write up a guide with your words on how to do it then let you post that. I did the same for some of the stickied threads. It looks like you're almost done and I think this would be a really good info thread once compiled nicely. Stuff like how to do OTG, what works, what needs a powered HUB, stuff like that. I personally will probably never use OTG, but I see the value and I like what it can be used for.
Best of luck!
That's nice. lol I understand I talk a lot, but when it comes to things I must have, like more than 5gb of memory on a device that should have a few TB . It would be nice for others to try out things to see what works and what doesn't. Because to have a powered USB Device is kinda not the point of OTG "On The Go". But like someone figured out that one of his older Flash drives worked, so hopefully others chime in too.
If you wanna do that, you have my approval. Just make sure it suits what I did, "Dedicated OTG". or "Guaranteed OTG". Since that's what I was mainly working towards. This discussion thread is mainly to locate what works and what doesn't and the main OTG Capabilities of the Kindle Fire2. I don't plan on changing much else to what I have already done except adding a larger psu to the hub so it charges the device while powering the hub and its devices for my own personal gain. I want to keep this open so people can throw up what they have learned as well so the information is out there for others. I personally hate going into a device and not knowing.

I should get an OTG cable. I have a small flashdrive, not sure about the name or brand since the size made it temporarily misplaced. It's the same size as the wireless receivers though for most modern mice and keyboard so it's SUPER small, which I actually wouldn't mind tucking the cable into my case, plus it's 32GB. The issue on PC, is the transfer rate is a little low, but that may be because it uses so little power, which I'm hoping.
Any good places to get an OTG cable?
Ebay, Amazon (great place for cables)

Just a quick search. You can also make one, if space is an issue. You just need a MicroUSB and a female USB. Pin 5 gets soldered to pin 4 on the MicroUSB and bam! Making one would help with space issues since you can tuck the wires easier. If you are good at soldering.

Is an OTG cable special or just F-USB and M-MicoUSB?
If it's just those, then I can go poke around Frys and Radioshack for one.
I don't know anything about soldering, how much is a good kit to get started? I think a friend of mine has one and knows how to use it, so I can ask him, but I realize it's something I should learn especially with the hardware mods I would love to do. If I can't find a cable in stores, or if it's special (I ask that because most employees at frys and whatnot aren't very helpful or knowledgable, so I don't want them giving me something that won't work, but if it's just those ends I'm looking for, I can do that) then I may just look into soldering my own and learning that. I see they're around $50 online but I don't want to screw myself over there.
You can chose a decent soldering iron anywhere from 15 to like 80 bucks. I recently saw some nice ones with adjustable power levels for good price. And tons of different tips. My brother Skorpn has the more expensive one that heats up fast and has adjustable power settings to fit any projects needs. Hr has a nice soldering station I wish I could use more. I however just have a cheap harbor freight iron with a fine tip from radio shack and I use the thinnest silver solder avail there as well. Flux is also a must.
Anyway. Otg mode is accomplished on the micro USB side. They have 5 pins instead of 4. The 5th is used for doing all sorts of things with the right add one tho. If you solder in a small wire to it and jump it to pin 4 which is ground, it turns on otg. Not really hard to do. You can make one decently. Just need a good micro USB cable and a female normal USB cable. Solder them together and then do the otg modifications.
Other than doing it yourself, they are very cheap. But if you have the spare cables, it doesn't hurt to play around.

I've got my USB mouse to work using otg cable, is there any chance using it could damage my kindle, this Mount app I use says it can damage the kindle because of the power output

I don't know what ap your talking about. But no. The Kindle Fire 2 only puts out half the voltage when in OTG Mode. So only certain things will work without additional power. Your mouse will work just fine, especially if its a wireless mouse, since the wireless device doesn't require hardly any power. Some other devices will work too. You don't need a mount app for using devices, only for Flash Drives. And so far out of every one I've used the best one is Chainfire's StickMount. Chainfire is the creator of Superuser.
Anyways, I'm not using a 2a charger to power my USB OTG Hub, and it powers all 4 devices and charges the device with ease. Cannot wait to have this thing installed.
OTG testing
After reading this thread I thought I would have a go and do some testing myself. so I found a USB y cable teamed that with a female to female USB adaptor so it would extend my OTG cable but allow me to pipe in some power (5v off a arduino) off the y cable. I have got my mouse working and USB flash drive but I cant get my Xbox 360 wired controller to work

You know the amperage of the power source you are using? It might just be not enough power. Because the device itself will take from it also. Its pretty much splitting it. Which is why I went with a legit Galaxy Tab 2a charger since its one of the most powerful chargers I've come across. I hope it works. Since bluetooth doesn't work on the OTG yet, I need the 360 controller to work. I will be trying a wireless controller and one of those Microsoft adapters soon. Hopefully it works! I'd love to play some video games in the car

You have a good point there, I haven't tested the amperage that comes out of a arduino but I don't think it would be much. I could try and hock up a iPad charger which I think is 2amp.

I have just tested the Xbox 360 controller being powered from a iPad charging plug and now joy. It lights up but then goes off
I'm making my own otg cable tonight if the spare usb cable I found works for data and not just charging. Basically I have a female usb port on a cable that I used to splice in with an original Xbox controller plug to be able to use usb sticks as memory cards for my Xbox to be able to install gentoo Linux on my Xbox (original Xbox controllers are usb 1.0 with a proprietary plug type) so I know the female port works fine for data transfers.
Eventually I'll buy some plugs to solder onto both the usb and Xbox cables so I can yank the female plug from the otg cable and snap it right onto the Xbox plug instead of having to constantly re-splice them or buy a new usb extension cable for the female end/buy a pre made otg cable.

Oh yeah, the point to my post was that I have three usb hubs, two powered one not, and a ton of stuff to test with my kf2 like a billion usb keyboards, mice, storage devices, and the one I REALLY want to get working, my afterglow Xbox 360 controller for minecraft pocket edition

Support any KF2 ROM Bluetooth Dongles ? (to use BT headset)

IDK how thats going. I don't think anyone is working on it since the KF2 doesn't have bluetooth to begin with. When I connect my cheapo BT Dongle, it doesn't allow me to turn the switch to on. However it does see the BT Dongle and thinks its a keyboard of some sort. Which would be nice because I have a really nice BT Keyboard for Android I wanna use.
Also would be nice to use PS3 Controllers. I'm going to attempt the wireless 360 controller with the adapter one of these days, whenever I can focus some cash in that direction. I really want a wireless 360 controller on my KF2 so I can play some of the higher end games as well as the older Emulated games. Just think its too cool
