USB Adapter with a USB hub

Hello all,
I received my USB adapter from Samsung today and am pleased to inform you that it works wonderfully with a USB hub. My hub has 4 slots on it and the tab was playing well with multiple USB devices being plugged in.

Really? I guess usb hub is needed to make things work? i had all kinds of issues. Mainly, not reading some usb drives, and memory reader. I just plugged the usb drive, directly into the usb adapter. The memory card reader was connected by standard usb to mini usb cable. That didn't work.
I got to try this.
Thanks.

No problem. I actually have not tried storage devices yet, only input devices. I posted on your other thread as well.
I have a feeling thumb drives may be having a problem if they are formatted in the FAT32 file system. I am going to try an NTFS drive and external hard drive and will let you know my results.
UPDATE: It appears I had it the other way around. I plugged in an NTFS drive to no avail, then formatted it to FAT32 and it worked.

FAT32 works great. NTFS is completely missing from stock kernels, it's in pershoot's "lib" extra modules archive on his kernels. However, I tried an NTFS drive using the extra module and it failed. (might require some manual mount magic???) It would take a lot more work to get FUSE working properly, and that's needed for the (vastly superior) ntfs-3g driver.

So does it work with external usb hard drives (both self powered and plug powered) of the sizes of 500GB and more?

what brand/type
what brand/type of usb hub do you have

If the hub is powered then the drive should work fine. You just can't use a usb powered drive without a power source

Ican't get mine to read my game controllers. Says something about high powered device. It won't let me read the message. When I tap it to make it bigger it just goes away. I am very frustrated. Can you get a fame controller to work? I used ps3.

PS3 controllers require a special driver. It may also require too much current since it tries to charge via USB. You'll need a powered hub if that is the case.
Gonna try my PS3 controller in a few minutes.
Edit: So far:
No excessive current errors from my PS3 controller - however mine has a fully charged battery because it's been plugged into a PS3 that has only been playing movies/videos for weeks. However button presses aren't recognized by anything. My guess is that if I dmesg I'll get an unrecognized device error. PS3 controllers are nonstandard.
However a Nyko AirFlo controller worked fine in SNES9x EX. It was semi-recognized by SNESoid - the keymap screen recognized something was being pressed, but games themselves wouldn't register presses.
Edit 2: PS3 controllers require the hid-sony kernel module to be loaded. This is included in pershoot's optional "lib" archive with his kernels. I had to hit the PS button to get it to turn on and start sending presses to the tab. No excessive current errors, but my controller was fully charged.

Thanks. But for some reason the ps3 and the x box controller worked for the xoom. I called samsung and they don't have any help for this issue yet. Can you get any external device to work for at least over fifty percent of what the adapter is meant to do? Did you get any error messages. I get high powered device connected. Then it say underneath that out could not connect. Device needs............. I cant read the rest. When I tap it to enlarge and read it disappears. Samsung can't figure out why that is happening either. Plz help.

Make sure the PS3 controller is fully charged before you connect it. If it isn't, it'll try to charge the battery and that's probably what sets off the overcurrent protection.
As to it working with the Xoom - I'd be VERY surprised if it worked with the Xoom when stock. Not so surprised about custom kernels, adding those modules is one of the first things people add, and the Xoom guys may have figured out module autoloading.

Thanks going to try now

wish i'd have read this before i bought it. i assumed it would since every other android tablet i have/had can power my external hds. pretty much makes it useless for me now as i was hoping to use it as external storage and for easy, quick file transfers. tf, xoom, and archos all work fine.

It works on a stock 3.1 build, it was one of those new features hyped at google i/o. I have both the European XOom and the Galaxy tab. The xoom copes fine with the ps3 and my other usb only non brand gamepad. The galaxy tab give me the hipower usb device error.

For SNESoid, you probably forgot to go into the other settings menu and turn on external input. The names may be off, but in addition to setting the key mappings, you have to turn on another option for it to see additional input devices, and then your gamepad will work

I had troubles reading an SD card with an old USB reader I had lying around. It was hit and miss.
Then I bought this SD card reader at Fry's for $4.99 and it works perfectly.

So, just to be clear, you are using a male A-A USB cable with one end plugged into the USB adapter on the GTab and the other end into one of the available USB ports in the hub, right?

USB OTG host mode (ANY USB keyboard support!) TUT

USE ANY USB KEYBOARD WITH YOUR USB OTG SUPPORTED ANDROID DEVICE!!!!
I've been experimenting with Wifi cards and the samsung galaxy sII
and realized people where having the same problem as i was having with plugging in usb keyboards.
turns out it all has to do with a vendors permission issue. if your device is not in the list, it will seen as "unknown".
As it turns out you can simply add your device and it'll work. mind you it was to be a simple input device and will have the power constraints of 100mW. But if u can compile a driver and splice in dc power.... skies the limit!
steps:
1. Android must be rooted (not going over that) and must support USB OTG (on-the-go)
2. You can either buy a USB OTG micro to female adapter on ebay for like 4 bucks. i decided to make one myself since i have lots of spare parts.
Heads up: a simple micro usb to female usb connector IS NOT THE SAME AS A USB OTG CABLE, they may look the same but the OTG cable has Pin 4 grounded to pin 5 on the micro usb side. This is how the device distinguishes aach type of cable. WARNING: IF MAKING THIS YOURSELF DO NOT CROSS BLACK AND RED, this WILL fry your PHONE.if you don't know you rway around a soldering iron, just buy one
3. Check what manufacturer your device is on this chart, if it's not there, check on the internet or plug the usb device into a linux box and run "lsusb" in the command promt and look for your device, the number will look like this:
Bus ### Device ###:ID <THIS ONE!>:<more numbers> " Company"
here's the chart: (taken from here :http://developer.android.com/guide/developing/device.html)

eg my keyboard is lenovo , so code is 17EF, you get it
4. log in as root, mount system as read-writeable, Create this file: /etc/udev/rules.d/51-android.rules
if its already there, then just append the command you want after.
if you dont have root explorer or otherwise installed here is how to in bash:
Code:
su
su
mount -o remount,rw system /system
mkdir -p /etc/udev/rules.d/
cd /etc/udev/rules.d/
now in the "51-android.rules" file add this line (or more for more device support):
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="<VENDOR CODE>", MODE "0666", NAME=="<VENDOR>"
my example with my lenovo keyboard:
SUBSYSTEM=="usb_device", SYSFS{idVendor}=="17EF", MODE "0666", NAME=="lenovo"
save.
5. plug in the USB OTG cable and plug in your keyboard or other device. it sould say "usb host cable" then "usb device".
on some keyboards the numlock light wont work, due to the fact of power contraints on the phone, you can add support by plicing in 5v DC in to the line (soldering needed) or you can probably jsut attach a powered usb hub
And thats IT, now you can actually type documents at a reasonable pace, without paying an arm and a leg for a supported bluetooth keyboard!!!

wow really good work.
just another info on the price of an BT keyboard:
http://www.amazon.de/s?ie=UTF8&search-type=ss&index=ce-de&field-keywords=CHIN FAI
40 euro are not an arm and a leg
and this i ok to type on

Indeed, you can get some BT keyboards quite cheaply. I already have one, but I'd still like full USB keyboard support (I don't always have my keyboard on me, but lots of people have USB keyboards).

I tested this on an unrooted SGS (Logitech K340 unifying keyboard) and it worked fine without having to change any settings. Just plugged it into the USB OTG adapter and then plugged the adapter into the phone. It said the device was unknown but the keyboard worked when I went to type in the apps. Mice also worked. The logitech MX Performance worked fine. A bit weird seeing a mouse pointer on the phone though.

How about keyboard remapping?

At first I thought:

*lol*
No, seriously, this information is VERY usefull and might open up the way not only for keyboard (as the OP stated, "get a driver compiled and the sky is the limit".
Will definitaly bookmark this thread and when I'm done with some other tinkerings try to "get the drivers compiled"

i know it's not expensive, but i'd really rather use something i already have, i've got a small flexible usb keyboard which works great.

As I'm trying to add joystick support on SGSII, I tried to add an xbox 360 controller and my device was not recognized. I tried this method and added "045E" as vendor but no luck, still not recognized... Any idea ?

Thanks. This is so cool and I gotta try it at home later (Tried 2 different keyboards at home before but didn't work). Hopefully you could find a way to use PS3 joystick as well.
Maybe we collect a list of device code and update it a single file. Then rom developer can incorporate it into their roms.
Don't worry about post counts. The is definitively a very good finding and development progress for S2.

We might have more luck with generic USB gamepads. I think all we need is someone who has the required knowledge to compile joydev.ko for our kernel.

My skill is quite limited too but with some reading it's not that hard (and I can give some help too).

I am looking for support for my Plantronics USB Headset. I am able to control volume through the headset when connected to OTG, but can't route audio through them.
I believe we do need generic drivers for USB Headsets. Hope one of the elite developers can help us. I will be happy to donate 5 euros for the same
Also, my Microsoft Wireless combo (Desktop 6000 v3) do not work while my wireless mouse 1000 do work absolutely fine on the Phone.
I am also looking for NTFS Mass Storage support which seems to be currently limited to FAT32 (and possibly FAT16) only.

There is a solution for that already. Search ntfs-3g or posts started by me.

Okay i could get the usb id from eurocase (i've a keyboard+mouse 2.4ghz pack) It's 1D57. Now when i connect the recivier, says "connected a usb device". But when i try to use mouse or keyboard it get stuck on one letter. I've try with a genius keyboard also (ID 0566) and it does the same... the only device that it works is a Razer mouse (without doing a thing)

My Microsoft Wireless Mouse 1000 works perfectly fine. However my other Microsoft Wireless Desktop combo (6000 v3) doesn't.
Also, I am looking for a way to use my USB headsets. I am able to control volume through it, but can't route audio through it.
Hope one of the devs here would be generous enough to help us get our devices working

Writing a driver and firmware from scrarch is quite a bit more arguous than finding one that works with linux. Look for one.
Once I get this porting business figured out ill post a tut on porting. Maybe even a small vm of the ubuntu box, to avoid rebuilding the setup

OTG through a HUB

Hey! So i managed my S2 to work with an OTG adapter. Now it recognizes Flash drives, USB mouse and keyboard as well. My problem is though, that i'd want to use both the mouse and the keyboard simultaneously, and later on my tablet as well.
I've got a USB hub which was pretty cheap i guess,
ht tp://itmedia.sk/item-images/other-usb_omega_hub4portSTARpowercapable/it6818_2.jpeg?nc=032
When i connect it to the OTG adapter it lights up, and if there's a flash drive attached to it when i plug it in, the phone recognizes the flashdrive without problem. As soon as i plug in a second flash drive, the light goes off from the HUB and both of the sticks get unrecognized. Also, the mouse nor the keyboard works through the HUB somehow..
I need to buy a specific hub with OTG support or a power hub perhaps? Could anyone help in this? I looked over google and stuff but people seemed to say different stuff at almost every site.. Thanks!!

Oh well that's quite interesting. Then you're saying this piece of video could be fake perhaps?
Since i can post links yet, search for this on youtube: USB HUB Support On GALAXY S2
Check the very first video.

I'm convinced that the every phone can handle only one device connected at the same time.

Well, it surely doesn't seem that way, that's why i was asking, since it's possible.

Weird.... i got sgs2 and 4-port usb hub and when i connect 2 pendrives to hub and hub to phone everything works good (i see UsbDriveA and UsbDriveB). If your hub have dc input you can try connecting power supply to this hub. Maybe this hub isn't compatibile with your phone.

OTG - On The Go

As the thread title states, I want to find out if the Wileyfox Swift support USB OTG? I have tried attaching a USB flash drive via the cable that used to work with my One Plus One that I had, but it does not respond when connected to the Wileyfox Swift. Any ideas? Thanks for any help!

Ill test it in 15 mins and get back to you.
I think I might have used OTG via TWRP recovery, but don't know about the ROM

Thanx for checking this. It would be great if there's a way to get this to work but I also wouldn't be surprised if the phone cannot support OTG.

It doesn't look like it is configured for OTG. It might be changeable via a custom kernel going by Chainfire's USB Host app.
I did not try the 'fix' in the second app as I don't have a current backup.

It might also not work because you have a wrong OTG cable since many microUSB cables won't work with the Swift

You might want to try using externally powered usb hub or Y shaped OTG cable to power the flash drive. I don't have any at the moment to try. Most likely it will turn out that the microUSB on the phone doesn't have the wiring to provide power (as it was for Nexus S but can be used if powered externally).

Maybe anybody can make OTG support in kernel and it will work with Y cable like on Nexus4?

Thanks for the update. As I stated in the beginning, I am not surprised that Wileyfox Swift doesn't support USB OTG. It's still a good phone despite this omission.

While the kernel that comes with it does not support USB-OTG, it is not impossible that a kernel with support could be built. The APIs are there, they just need instructions to call them.
I'm not too fussed about it, if it had no portable SD card support I would be annoyed, but having the card allows much of the usage cases of USB-OTG.

USB OTG/host function does not seem to work anymore?!?!?

I recently received my Lenovo / Motorola Moto Z Play and I am very happy but....
the USB OTG/host function does not seem to work anymore. This has worked fine from day one, but last Saturday suddenly no longer. I have no idea why it no longer works, there was no update, and I have not seen or heard weird things or done anything to it.
When I insert my USB C type SD card reader, nothing happens anymore. The LED of the card reader / stick doesn't even light up.
Preferably I solve this by myself, but I have no idea what to do, I did a factory reset but that brought no solution.
The data connection to PC and charging function both work fine.
It seems that the telephone does not power the USB port (anymore?), but I can not test it. All cables/adapters/SD cards/USB sticks do work in my other phone, so there must be something going wrong in the moto Z Play.
Can anyone advise me? Does anyone else have this problem too?
I need this function during my work occasionally.

Here is what support for USB Audio player said in response to why the app cannot see my drive:
Android basically does not support USB drives. Some file explorers have made their own USB mass storage driver and FAT32 handler. They set up a local HTTP server for other apps to access the selected file.

Yeah, well guess what, that may be true, but it WORKED and then since last saturday it doesn't anymore. If I use a powered cardreader, it works again, and same goes for connecting a USB mouse or keyboard.
To me that means that the power supply to the USB port is defective.
Does your Moto Z Play support a USB mouse? Please let me know, cause that would make my case.

Hmmm....
Post a link to the product that stopped working?
I had funny behaviour about internal storage being seen by Jetaudio. It played from /music for a while then it quit being able to find it (as well as most of internal) a reinstall does not help.
I think only a firmware reflash might reveal a problem....
You could help me too. See if my complaints about OTG drives is true for you also. Do you have an OTG / memory stick adapter? If so post that link too.

The only product that stopped working is the power on the USB C port from the Moto Z Play itself. I have checked all cables, adapters, USB sticks, card readers and mice, they ALL work fine on other phones.
I can't check for you, since I can't connect to USB card reader anymore.... In my case it's simply the power that isn't provided anymore on the USB C port, while earlier it worked ok, therefore it must be broken. I'm going to have it fixed with the seller.
In your case I would say try ES file explorer or TotalCommander. Both did work great (until the power issue).
If you can use a mouse on your Moto Z Play, then you're OK. OTG should work fine then also with ES or TotalCommander.

Same problem happened to me.
After few days back, all seems to work fine but suddenly same OTG USB stopped working.
Kindly let me know how to solve this problem if anyone has done it.

Hello, I have the same problem, OTG used to work normally before. Now I found out the only way to make it work is to supply the 5V power from an external source using USB extension cable with a extra power plug (2 males, one female), which I plug into a powerbank/wall adaptor. Not perfect, but still better than nothing, OTG seems to work.
