Hi, not managed to find any info regarding whether the OPO can act as a USB host using the micro-USB connector and an adapter (micro-USB male to full size USB female) cable.
I've an i9300 adapter cable - generic brand, not Samsung - which works perfectly on my S3, can connect USB flash drives and it also powers 2.5" disks without any problem.
Don't want to risk plugging the adapter cable into the OPO unless I'm sure its wired correctly, and havent found any OPO adapter cables for sale anywhere...... so wondered if anyone knows the pin assignments of the connector, or has tried an external disk adapter cable?
Give it a try and see what happens, worst thing that can happen is that it won't work, I have made one a few years back and then replaced it with a Nokia OTG cable and works fine (I've used this cables on all the phones on the signature). I don't see why it will be wired differently from any other, companies work with "standards" so things like this are compatible across all phones, unless its Apple.
Thanks for the reply... you've solved my problem, I hadn't included "OTG" in my search terms. Oneplus do have a cable listed, and other sellers list a single cable claiming compatibility with just about all phones - including i9300 and Oneplus.
Plugged it in and it works fine with a FAT-32 card Doubt whether ext / reiserfs support is there, but may have been compiled in to a custom kernel.....
Doesn't manage too well where disks have more than one partition - if the first is reiserfs and the second FAT32 it fails to mount. Assume first partition must be FAT

Quite a lot PDAs supporting USB-host, but for only a few an adapters or appropriate cables from the manufactures are available.
As these devices support USB-Slave as well I would like to know if there's a way to convert the USB male connector (used as slave e.g. for sync with the PC) to a USB-host female in order to connect accessories (keyboard, mass-storage devices...).
According to wikipedia the configuration of the pins shouldn't differ too much for slave and host mode.
Pls. see attachement, that's what I found regarding this question. It's a picture showing a similar configuration (as new user I'm not allowed to post external links, thanks to ab21cn
from xdaflameusers)
But it's a male-to-male converter and furthermore a converter from "big usb" to micro (mini?) usb. As there're already standard converters for the different sizes of USB I would like to start with the biggest size and to buy the appropriate converter as needed.
Does anyone has a circuit diagram or any other idea for such a generic converter?
Try adapters made for Nokie N800 series
I had a Nokia 770 a couple of years ago. It came as USB device only with mini USB connector, but online I found how to upgrade the software to USB host, and use a cable adapter. The plans I found online involved a 9V battery and 5V voltage regulator inside a metal case (they used a penguin mints case). I built one of those, even using the penguin mints case, and it worked fine.
I have never seen any indication that my HTC phone would work the same, but I am guessing that it might, if the USB host drivers are available.
Google couldn't locate the penguin mints-based converter I originally found, but this seems to be a similar circuit diagram.
Edit: Found it!
thx
thanks for the links. but i'm a little bit afraid of connecting something to my pda which has an own power supply, the risk of a burn-out is given. i've got a nautiz x5 with 4400mA battery which should have enough energy to supply usb-power to connected devices.
I think I'm going to contact the manufacture of my device, maybe this works for me, but a generic adapter would be of use for anyone.
the chips used for usb should be of the shelf as i don't think each manufacture develops an own logic for usb... but this doesn't imply that the cabeling is standard too.
what the heck makes manufactures providing features in their products which the users can't take advantage of?
do you mean using keyboards and so on on ppc?
because it's so simple if ur phone has a mini usb plug (the one u plug the power adapter into). i found a cable that plug into that and plugs a normal usb cable in on the other side and blam been typing on my phone using a desktop keyboard. it depends how much power your device requires however. i wish there was some software to feed a video line out so i could watch videos on pair of vizors that wud be rad. all i can find is a mini-sd card converter now whats the point of that. guess i need an itouch
yes
primary i want to connect usb mass storage devices to my pocket pc. gamecontroller or keyboard would be a good thing too.
my devices doesn't have a standard usb plug, the only thing i got is a adapter from the properitary plug of my device to standard usb male connector, but this is meant for usb-slave use only.
the underlying qeustion is, if there's a way to convert usb-slave to usb-host using the same pins. if it needs an additonaly pin then i don't see a way to convert it as i don't know anything about the pins cableing of my properitary plug.
a week ago i found an adapter which was able to convert the male usb to another male usb... but it didn't work.
the problem is compareable to datatransfer between two pcs via usb - it's possible, but only using properiatry hardware and drivers...
so i think there's no way to solve this problem in a generic way.
out of interest, do you already have windows CE drivers for the device to act as a host and mass storage? I wouldnt mind them if you can point me somewhere..
how to check if my htc (touch2) ca use usb host?
Anyone know if it's possible to use MHL in conjunction with a microUSB to USB host adaptor to output to HDMI and access an external USB drive at the same time? That'd make the SGS2 an amazing portable media unit.
No, it is not posible. Its an either/or connection to the micro USB port.
Shame, because as you say that would really be a great thing. MHL consortium are considering a number of improvements to the 2.0 MHL spec, so in future devices this may be a possibility.
So MHL can't be used when I'll plug a USB-Hub?
No, sadly not.
It's a shame - for now I'd prefer micro USB & separate HDMI port so USB can be utilised as well as an external display.
As would I, and a lot of others I suspect.
But you've got 16 GB memory and can copy your stuff to the memory and watch it later via MHL on your Flat? So this is not a big problem, I think

Yes, but 16Gb of FAT32 and you can't copy a file > 4Gb
I would use allshare to stream the movie or whatever to your phone from a laptop and connect the phone to TV via the MHL HDMI adapter...that way you have access to ur laptop's data without being hardwired to it

Not that I'm aware of...
I bought one from Ebay and can't really do anything good with it. Display shows briefly for 3-4 seconds on TV then disappears again. Don't know why.....I hope it's not the device itself because I tested 2 phones, they were bought at the same time, but none of them would work correctly....
If by generic you mean a not samsung one or one not dedicated to the SGS2 then i actually use a one, from ebay or someting like that, everything works perfect you just cant forget to plug power to it, and about the not working one, it seems mine gets jammed by gsm signal (i.e. when receiving a call), so from time to time the image disappears in a blink of noise, maybe that is your problem too, try it in airplane mode.
Oh, I think I misread that question - I have actually used a generic one with my SGSII (a prototype from the MHL consortium) and it worked fine!

Uhm no. I've been streaming with WIFI through MHL no problem for MONTHS. Using the Original Samsung MHL connector of course.
I have to put mine in offline mode to be able to use the MHL adapter.....
As for USB-OTG no luck yet.....
On Amazon, Ebay, DealExtrem ... you will find adapters that can do 3 things at a time:
- output HDMI
- let phone work as usb host, so that you can plug kbd, mouse, and external HDD (second wifi card, wired ethernet ...); once you have the usb A plug, just pub a hub
- recharge the phone (what is not possible with the legacy short OTG cable).
+ read memory cards
Such devices are sold as MHL devices. Some MHL devices don't to all that.
Take care. MHLv2 is more complex than MHLv1.

Could you post a link as an example for such a device, that works properly (if you've tested, or you know it works) ?
Thank you
I can post links, but ... I have not tested any of those. And don't know any one personally who tested it.

Monobloc:

I don't like the monobloc version; I fear it's too heavy, and may help breaking the phone plug.
There are all sorts of OTG and MHL cables. I have seen OTG dongles as short as 4cm (monobloc), with small cable (8cm: 4-8€), with long cable (1.5m .... should be 7 feet), pure HDMI (passive cable, no card reader, 8-12€), VGA (including very cheap HDMI to VGA converter, 20-30€ ... including sound output). In some case, you need to buy accessories (extra power supply, extra uUSB cable, extra HDMI cable). Also seen a very cute hybrid card reader: http://dx.com/p/285865 (I love this product design, and I love this URL syntax )
Don't forget that there can be mistakes in item description.
Here I have described how to build an external battery:
http://forum.xda-developers.com/showpost.php?p=54036759&postcount=17
On previous phone, I just soldered additional battery to internal one; on my new phone, I will do something more complex, and more flexible.
Loosing power via OTG/MHL is not a fatality. Most phone have an other hidden power input:
généric, that uses the USB plug:
http://www.dx.com/p/reverse-qi-wire...arger-receiver-for-micro-usb-cellphone-312805
TRIPLE CHECK POLARITY; I took the wrong one; have to fold the cable.
So ... even if your OTG/MHL module takes power from your USB, and can not recharge your phone, the specific shell can charge your phone the other way So, you need to build an internal specific module:
https://www.youtube.com/watch?v=UK7PRJ4SiK0
S2 specific back shell, so called receiver:

http://www.alibaba.com/product-detail/QI-Wireless-Charger-for-Samsung-Galaxy_821969998.html?s=p
The SGS2 is not designed to accept wireless chargers, so, you have two options:
- solder and take the pins out (cf youtube) (do not solder coild to battery, or you could overcharge the batt, and burn your phone ... I mean, physically set fire)
- find an item that includes back shell + specific battery (exportprive)
Many recent phones have the internal connectors, so you just need to change the back-cover. In this case, the software will be able to know the charger is wireless (as opposed to AC, and USB; advanced battery tools will show those 3 possibilities). I believe the motherboard for my HTC One M8 is designed to have those pins, but I can't find the specific cover yet (maybe in a few months); only found it for M7.
I can connect USB sticks to my phone using a USB On The Go (OTG) cable which is basically a microUSB to USB adaptor.
That's great but I am looking cleaner solution. Is there a flash drive (such as USB stick) that has a microUSB male connector and can plug straight into the microUSB socket of my phone. There are plenty of adaptors and microUSB card readers but no microUSB flash drives, it seems.
I have seached all over the internet to no avail. has anyone come across such a thing?
bump, i really want one of these
BUMP!!!
I imagine a tiny flash drive where you can remove the USB plugin/cover, and underneath, see that it is meant to connect to a microUSB port.
Would be awesome for Android (Nexus, Skyrocket, etc...)
I found this thread since I am about to get my first nexus device but have literally never thought about this before now. That may give you some indication of how small the market is since most phones come with expandable memory. However, when I consider how many random ass devices and connectors you can find strolling through an electronics store, I honestly can't understand why someone hasn't built this yet.
Not sure if this is the correct place for this, first time posting.
So I'm having a hell of a time getting my Western Digital 2TB external drive to connect to my Nexus 7 2013. I have both Stickmount and Nexus Media Importer installed, and I'm rooted with Cyanogenmod, and I have a working OTG cable.
I know that the Nexus 7 doesn't have enough power to support most external hard drives that use a USB for power. So I bought a 12000mAh external battery with a 5V 2.1A output USB port, and a 4-port (unpowered) USB hub from Radioshack.
Along with those, I had to hunt down a male-to-male standard USB cable in order to connect the female port on the hub to the female port of the OTG cable (using the standard USB-to-micro doesn't work, because for some reason the OTG cable is specifically required to mount USB devices on Android, as you guys probably know).
After finally getting the male-to-male cord today, I tried hooking it up and still no luck. NMI detects the OTG cable but cannot detect the external drive. It works just fine with a flash drive.
Now after looking at the reviews of the USB hub on the site that I linked to, I'm thinking it may be the problem. If you look in the comments you have multiple people stating that this specific hub doesn't play well with many external drives. I haven't had any troubles with it through my PC, but you never know. I've also tried switching between the USB 3.0 cable that came with the drive to a standard USB-to-micro charge/data cable (with no luck), because I've read that NMI doesn't support USB 3.0
Does anyone have any advice or experience with this kind of thing? I'm thinking I may need to find a Y adapter that has one female and two male plugs so I'm not having to go through a potentially-crappy USB hub. But I'm not sure if that'll actually fix the problem or not. From searching around on the web a bit, it seems that connecting this specific drive with the Nexus 7 shouldn't be all that difficult, there's plenty of simple guides out there to demonstrate.
Just to recap, here's my connection process:
- Connect USB hub to external batter (2.1A port), make sure battery is ON
- Connect USB from External Drive to an open port on the hub
- Connect male-to-male USB cable to another port on the hub
- Connect M2M cable to the OTG cable
- Connect OTG cable to Nexus 7 (while on, with 90%+ battery)
- Nothing happens
EDIT - Would have included links to the specific devices, but I'm new to XDA so they won't let me post link yet.
I have a WD 1TB USB3 external drive. The only way I got it to work was by installing Paragon exFAT, NTFS & HFS+ (Available on the Play store), connecting the drive through a normal OTG cable, and rebooting the Nexus WITH the cable connected. Yes, I have to reboot every time with the OTG cable plugged in. I can plug/unplug devices as much as I want, but once the OTG is unplugged, I have to do another reboot; it's annoying, but it is better than nothing. Give this a shot.
Also, what ROM/Kernel are you running?
is the drive formatted as NTFS or exFAT? maybe try the ElementalX kernel as it supports both formats for USB OTG and see if that helps?
http://forum.xda-developers.com/showthread.php?t=2389022
edit- just remembered that i came across extra files on the Stickmount XDA page a while back that lets Stickmount support NTFS and exFAT drives, if flashing a custom kernel isn't your thing then you could try that..
http://forum.xda-developers.com/showthread.php?t=1400034
I finally got it to work, and now I just feel foolish.
I just needed to switch two cords. I had the male end of the USB hub plugged into the battery, and then the external drive and male-to-male USB plugged into the hub. The male-to-male cord then went to the OTG and the tablet. This apparently didn't let the data/power through correctly.
I went down to the local computer shop and the guy showed me that I was doing it wrong. Instead of using the hub's male end to hook up to the battery, I needed to use the m2m cord for that. The male end of the hub now connects to the OTG, and it works like a charm. I have to make sure to power up the drive and give it a second before connecting it, but Stickmount detects it right away and I have all my content.
I was pretty sure I'd tried every configuration and that I'd need a Y cable for sure, but I'm glad that's not the case even though I feel like an idiot now, haha.
Hey Guys,
I recently bought a Micro to USB OTG cable but unfortunately can't get it to work on my new S Tab(10.5).
I am able to get it to work on my Galaxy S3 phone and old Nexus 7 tab so it appears that the cable works fine. My S Tab is not rooted and currently does have the latest updates. I also ran the OTG checker which verifies that my tablet has the necessary files. When I run the OTG troubleshooter tho it does not appear to be picking up my cable at all.
I originally bought this to use my wired 360 controller on my tablet, the 360 controller and flash memory sticks are the only things I have tested on the cable itself. Like I said above, my S3 and Nexus 7 picks up these 2 devices just fine through the cable.
Anything that I am missing? Any tips/quirks to get this to work?
Thanks so much for your time/help!
P.S. attempted to post link to my exact cable but couldn't because I am a new member.
Are you willing to have device root and flash a custom kernel?
If yes, then my SkyHigh kernel does support OTG and has in-built XPAD (XBOX) controller module and confirmed working by another user. Some games may require you to map the controller with a certain app, some without.
FS support is dependent on kernel. If you are trying to mount NTFS r/w, then you will need to also install Paragon app or navigate to /mnt/ntfs/.... for kernel NTFS r/o
It's possible that it could be your cable. I had problems a couple years ago with an otg cable not working on my Note 2 but working in a couple older devices. It turns out it was because the micro usb end that plugs into the phone was too short to plug in all the way. I'm not sure if it's a new standard or something, but my Note 2, Note 8, S5 and Tab S all seem to have a cable with a longer micro usb tip than any of my previous devices have.
Hold the otg cable next to the charge cable that came with your Tab S and see if the tip of the otg cable is a couple of millimetres shorter. Also plug the charge cable into the tab and notice the way it kind of "clicks" into place when you push it in the last little bit. Now plug in the otg cable and see if it has the same "click" feel. If not, then I'd bet it's your cable. I have an otg cable that specifically states that it's for an S5 and it works perfectly on all the devices mentioned above. I also have a generic otg cable that works on my old galaxy nexus but doesn't work on any of the above devices.
Here's the old thread in case that helps:

Thanks for the reply's.
I don't really want to go down the Root road because I have never gone through that process and don't feel comfortable with it at this time.
The cable Micro pin portion definitely doesn't fit as snug as the S Tab charger. The OTG cable actually appears to be longer than my S Tab charger Mirco pin. When plugged in you can tell it sticks out a smidge....The thing with that though, it does the same exact thing on my other 2 devices that work with the cable.
Guess it could be the cable, just hate to send this back and order another and be in the same boat.

Cable or no cable, if you wish XPAD controller, then you'll need the kernel or loadable kernel compiled module. Other features (some I described) also require kernel. ... all requiring root.
Since you've ruled that out, you just need to forget many features that are available with some other devices and move on.
Best of luck.
