Hello friends, I am new to this forum, but certainly not new to the tablet world. I purchased the iconia a100 a few weeks ago and I must say it is a superb tablet in almost everyway. That being said, I am trying to come up with a solution for the lacking usb host on this tablet. I am certainly not a dev, but I am wondering if there is anything in the works for a working usb host? Does anyone know if acer has any plans to offer an adapter or even a different docking station with the usb host working from the 40 pin? If anyone has any ideas or would like to start a project i will be glad to help in anyway I can. While i was researching this usb host problem i see that there was a very sinilar situation with the galaxy which has since been resolved. Any suggestions? Thanks
Not yet possible, but you can pretty much count on it to be baked into a custom ROM when we get the ability to fully unlock and root this device. Root is already possible, and done. Unfortunately, we cant really do much development on it right now due to the encrypted bootloader. Most devs are waiting for the ics update in January to get the ball rolling on tweaks and hacks to the a100.
Sit tight, they'll have you up and running in no time
ummmmm............ could you repeat that?
This is also #1 on my wishlist. However, I don't know if that is even possible with a custom ROM; it requires the hardware to support it and I don't recall seeing any teardown that states that it would be possible.
I've seen it done in various phones, but don't know if its been posted on any here, but I'm sure a search on the forum would help find them. Its a matter of reconfiguring the port in the programming and getting an adapter from micro USB to standard USB.
But don't quote me on any of this, I could be mistaken with other devices. There has been talk about USB hosting on the a100 before.
ummmmm............ could you repeat that?
Yes, you would need something called an OTG (on the go) adapter. The hardware in the device has to support host, so it is not JUST software.
I can confirm that i have tried the otg adapter as well as other adapters...and it only works as slave. I would just like someone to confirm that usb host is possible [that the harware supports host capabilities]. I am just glad to see there are more people interested in fixing this problem as this tablet is superfast and top quality in every other way in my opinion. Thanks again
Maybe something comes out of
http://www.circuitsathome.com/mcu/programming/android_adk_compatible_usb_host_library_release
I ordered an OTG cable and once it comes I will take a look at enabling USB host mode.
I am guessing that the hardware supports USB host, but will need a kernel module and some scripts to enable it.
I also suspect that the USB port will not supply power to an attached device. If this is the case, the workaround is to attach a powered USB hub to the OTG cable.
Crossing my fingers, and waiting for that OTG cable to come in the mail...

USB host is enabled in the kernel. Hardware does support USB host.
Acer left it off the board entirely, so I doubt much can be done without hardware modding, which I'm all for lol.

Sounds grim if the hardware connection is not there, are we sure that the port is just not supplying power?
do the kernel modules load? (e.g. usb-hid, usb-storage)
Has anyone actually tried to:
a) insmod the correct modules
b) force change to host mode (the device probably has to be either slave or host, not both at once)
c) connect something (e.g. a mouse or a thumbdrive) through the otg cable and a powered usb hub?
At least I won't have to build a kernel to test this out.

I know this comes up every now and then, I really dont know how far anyone gets before giving up. Feel free to try out whatever you want, while I don't care about USB host I know a lot of people do and would love an update on any progress anyone can make. Even if its just things that don't work.
Acer is generally lazy and cheap, we use the same kernel source as the a500 which has host, which is why we also have it. It could be modules, though I doubt its so simple. Also a powered hub would be needed, there is no power supplied to the port that anyone has found. This could be remedied with some hardware work I'm sure. The hub would also need to be one way, meaning not dumping power to host as I doubt the a100 will take it and without protection would likely suffer damage if the power pins are even hooked up.
The system itself runs at 12v though I'm sure there's a 5v rail someplace but if it can support powering anything past maybe a flash drive is unknown.
Take a visit to iconia-dev on free node, they'll know more of this then probably anyone here does lol
Tapatalked from my Galaxy S II.
The A500 does not implement USB otg, but rather a standard USB port. In other words, USB otg is not necessary for the A500 since it has a standard port. The USB otg standard allows a the port to act as both master and slave depending on the connection. In the A100 service manual, the schematic shows only one connection to the chipset (client), host is unconnected, which could be a problem. However, it is known that the Tegra 2 can support otg connections. I'm not certain, but it may be possible that by shorting pins 4 and 5 in the micro usb connector (ie, using an otg cable) and with the proper kernel level support, the A100 could still act as a USB host, albeit with no power supply to the micro USB port.
I'll continue to investigate this once I have a chance to build otg support into the kernel and recieve the otg cable.

Thanks for that, but one thing, its already in the kernel. However Linux society and/or waydownsouth would know more about what's in there, I just know it isn't blocked there. Modules etc I don't know. I look forward to seeing some progress on this topic.
Tapatalked from my Galaxy S II.
Pulled the kernel config from my tablet, you are correct, otg support is built into the kernel.
I'm using ezterry's kernel, almost everything is built in, there are only a few modules that have nothing to do with this.
I tested with an OTG cable, which shorts pins 4 and 5 in the micro usb connector. As expected, this did not enable USB host mode.
I tested wtih 5V going into the micro usb connection, as some of the non-powered devices need that voltage applied to activate the port, still nothing. (and no damage!)
I added a few other things to the kernel, the dmesg output changed slightly compared ezterry kernel
When connecting otg cable with 5V, dmesg shows:
tegra-otg tegra-otg: SUSPEND --> PERHIPHERAL
vbus connected, lock wakelock

In the possibility that USB host is not possible on the micro usb port, a hardware mod could be done. There are points for a mini PCI-E connector on the motherboard (this is where the 3G module would be for A101). Solder wires to pins 36 and 38 for USB data, 4 for ground and connect them to a usb port. The PCI-E only gives 3.3V, but power could be supplied by a powered hub instead. There is even space inside the unit to mount a micro usb connector on the end with the power button.
The main roadblock is that the solder points are on the back side of the pcboard so you have to fully disassemble the unit to remove the motherboard. It would actually be fairly easy to do if the points were showing when you remove the back cover.
I don't think I have the nerve to actually try this.

Well if you want to play it like that, you can use a mini pci-e > usb adapter, which is also available with and without sata too lol. It would, maybe, depending on the board used, even line up with the sim slot, so minimal case cutting would be needed to make it accessible for usb. Straight drop in for an A101, though we lack the actual slot for it. Might be something I'll try later on.
Edit: I forget, does the sim slot line up with the pci-e slot? Been awhile since I saw the inside of one, so I may be wrong on that point.
There isn't an actual mini pci-e connector in my tab, it's just the solder points, so you would have to solder on a connector to use the adapter. The sim slot doesn't line up. But it looks like the empty sim slot is not high enough for a micro usb port to fit anyway.
I tried the hardware mod. Unfortunately the mini pci-e is not hooked up to the system. In other news, the motherboard is very easy to remove and reinstall.
there is a ROM in which they have implemented the usb otg?

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

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

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.
so, anyone taken apart an MHL adapter yet?
i have a sneaking suspicion, that the move to an 11 pin is what will allow BOTH OTG, and MHL at the same time, but i could be wrong.
look inside your USB port on the bottom of the S3...
whatya see?
the normal 5 pins on the USB part.. but what is that in back wall? THE OTHER 6 PINS!
yep, that is why you cannot plug the MHL adapter into a hub or anything.. there is 6 pins are missing.
Now, i am wondering:
has anyone taken it apart to see if the 6 pins are used alone, or if it uses the the USB also?
if it uses only the 6 pins for MHL-ness, then it should more than possible to make an OTG/MHL adapter/dock.
more thought says, if my theory is right, an 11 pin to 5 pin conveter may be the key.. and an otg can be spliced in to give 2 outputs: MHL in one (using an s2 MHL adapter) and OTG in the other.....
anyone wanna tear their adapter up? or are you guys gonna make me spend some money?
I ran across this post looking to see if anyone has done this yet. I am going to try to grab the 5 to 11 tomorrow and tear it apart (since it's the cheaper adapter). My plan was to rip it apart and if the original 5 pins are available, splice just as you mentioned.
I can't find a decent picture of the microUSB plug to see if all pins are there.
Also I found this:
http://homixtech.en.alibaba.com/pro...Galaxy_S3_11pin_To_Micro_USB_5pin_Gender.html
Which makes me think 11 pin microUSB plugs that work are available out there somewhere.

So, did you do this experiment? Has anybody found a way to get access to all of the pins and make OTG work with MHL?
I've been waiting for two months for an answer about this. I'm glad someone started a thread. I kind of have this hesitation to start new threads.
I would love it if this could be integrated with the seidio active dock.

meh, I think that is wrong. many people have done exactly what it says you can do, and it doesn't work.
Makes me wonder if the boys at Samsung made a press mistake. If indeed you can't use both with the correct cable, then why make a port with 11 pins? Seems a waste of resources to me.

I have never seen anything from samsung saying that MHL and OTG was possible.. just speculation in websites.
It better be possible because if not all Samsung's managed to do is make us buy hugely overpriced new MHL cables when they could have kept the old type, but I guess Samsung's made some decent money giving people no option but to buy £30 MHL cables.
I hope Monoprice really is working on a cable. 35-40 USD is more than I want to pay, especially if I get a couple and/or an HDMI dock.

Someone needs to find the resistor values first so the phone can use both simultaneously if it's even possible that is.

that would be key. I have sent out messages to people that may know, or may be able to find out, but i have not had success.
heck, If it can be done in the terminal (turning on items) i can make a shortcut that would do it.. but i have had no success with that either.
It's not possible I think.
You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?
You can split the cables from the samsung adapter, so you have the MHL ones(6) and the usb ones(5).
But what then?
You need to connect the MHL ones to an hdmi cable, and connect it with an MHL enabled tv. And the usb ones to an usb port for OTG.
But will that even work with this S3?, because it is designed to get power from your charger via the extra usb port on the adapter.
Maybe it only works with the adapter, and not even with an MHl enabled tv...
I think somebody needs to connect the S3 to an MHL enabled tv, if that works you can modify the adapter and use the usb as OTG.

Values are already figured out, but both MHL and usb output at the same time is not possible I think.
You can use an MHL enabled tv wich powers MHL, (so you don't need the adapter) but how do you want to split that?

I found (and shared) the MHL value, and we already know the OTG value.. but it only seems logical there is ANOTHER value to activate both at the same time. we are postulating, the the reasoning behind the 11 pin, is to allow both. If adding just an OTG cable turned on MHL too, it would cause issues without an MHL connection. and the same with MHL activating OTG, without an OTG device connected. like i said, this is postulation at the moment, but there SHOULD be a thrid value to enable both at the same time. that value would be used by a future peice of hardware that does a whole "PC MODE".
and if it does not exist, it CAN be done, we just need more "stuff" a way to enable a special switch if you will.
some people are saying you can connect straight to an MHL enabled TV, but that has not been done yet (and since there are no 11 pin MHL cables, that are not adapters, it seem unlikell that anyone will until said cable exists. the S3 cannot send MHL signal over the usb part, it has to be either the extra 6 pins, or with the 11 to 5 pin adapter.)
essentially, the pins are there, and with some special software, or a hidden resistor value as to yet, unfound, and some custom hardware (as of now NOTHING 11 pin, has 11 pins in it) it SHOULD be possible.
but there is nothing that has been found (hardware wise) that is even modifyable to work.... yet.
What I don't understand, why does MHL only work with the power connected?
They could easily make an MHL cable with the 11 pin, and hdmi. That should work for only MHL.
Only no go I can think is that MHL drains your battery because of always having your screen on, and the MHL output.
So they decided to use the adapter with power, otherwise you can't use MHL feature very long before your battery is empty
I think inside the adapter they only use the pins for giving power, and not the full 5 pin support for OTG, and therefore OTG doesn't work when you want to connect something.
Inside the ROM they have maybe build in something that MHL will only work when power is connected.
Maybe the solution is very simple,modify the adapter so full 5 pins are connected.
For those of you that have them... I have a question.
Is the USB micro connector in them the same as a standard micro USB cable? Or are they designed differently to minimize the insertion force that is typical of micro USB connectors.
I ask as if they are simply the same, it seems likely that a lot of stress can be put on the phone's port unless you are very careful when inserting and removing.

I have the Motorola PowerDock made by Griffin. Both the rear and the top are standard micro USB ports; however, the plug on the top that connects directly to the phone in the dock is on a pivot so the stress is minimal if any.

I produce the Lambda-Docks and did a little recherche on the net since people ask me about the ability to remove the doch one-handed. From the specifications I found it seems that the Micro USB is designed to have an extraction force of around 9N (! around 1kg).
We also have to note the the USB spec says that it is designed for around 1000 insertion/ectraction cycles.
My Galaxy Nexus isn't charging or connecting to my computer. I've tried different USB ports, wall adapters, and USB cords and nothing. I don't really want to replace the charging port. What can I do?
Thanks in advance.

Delete this thread!
I accidentally put this in the wrong section! Thanks!
Check the charging port for Lent and stuff with a little pin or something..
That's what happened to me in the past
I cleaned it out and start to work again

Of what cujo said didn't work you have no option but to replace the port or buy an external battery charger.

In a pinch you can rig up a temporary charger using the POGO pins on the right side of the phone. Just wire the corresponding red/black wires from a cut up USB cable to the correct pins (you can find the pinouts online). The trick is getting the wires to stay on the pins - you can try packing tape. I know this is kind of a dirty solution, but it will work in an emergency until you can replace the usb port.

Can you link me to the part I need to replace! And a video of how? And how expensive is the part in question? My Galaxy Nexus isn't my main phone but I just wanted it working again.

Well, there is no guarantee that it is the USB board - but you can purchase one on ebay for under $10. The part includes a usb jack as well as a ribbon connector that connects the jack to the main board. There is, however, a chance that you have a faulty main board, in which case, replacing the USB port is not going to fix your problem but the only way to really test that is to buy the part and try it out.

That's for a Verizon Galaxy Nexus, I don't remember which one you said you had but you'll want to be sure to get the right one.

Are you using the original charger that came with the phone? It's the only thing i have luck with.

I ordered the new port! But I tried the pogo port charging and it didn't seem to work.
