Hi
I have a new tablet (Medion Lifetab s10346) running KitKat that works fine with all sorts of periperals (mouse, umts-stick, hard-drive, hub) I have connected so far via otg.
And I have a Cherry G230 usb keyboard that works fine on my PC and my raspberry.
But when I connect the keyboard via otg to the tablet it is not recognized as a keyboard and does not work at all. The device shows up on the usb-bus (when I do a "lsusb" in a terminal) but that's it.
Even though the keyboard has a few non-standard multimedia-keys I would have expected that it would at least get recognized as a generic HID-keyboard....
Does anyone have an idea what the problem might be and if there is anything I could do to address it?
Many thanks!

Is there anything I need to do/install to get my mouse or keyboard to work on 3.1? When I plug them in, nothing happens. I've also tried plugging in my iPhone and an Xbox 360 controller, just to see if there is any response to any of them to show that the Xoom sees them.
I have a wired mouse and wireless keyboard (I figured keyboard wouldn't work). I'm trying to figure out if I may just have a bad OTG adapter.
Bluetooth keyboards work just fine.
You won't get any notifications or popups when you plug in a device, they will just start working (eg, you can just start typing with the keyboard).
Yeah I assumed they would just start working, but I wasn't sure if my wireless keyboard would work. I know when I am, for example, installing windows the keyboard works before drivers get installed, just not to the full extent.
I need help on this aswell... anyone?
I was wondering about this aswell. Doesn't it need to download drivers for the keyboard/mouse to work? Also since there's only one USB plug, would a hub work to get like a keyboard and mouse working at the same time?
And would wireless work?
good day to everyone. firstly, i would like to thank you for having the time to read my post.
well basically heres my inquiry, my unit is the alcatel tab t10. i never had any problems with it until recently, my device's usb port suddenly stops working.
tried unchecking the usb debug mode, tried checking it but to no avail, the usb still does not work. it doesnt seem to connect to my laptop. tried changing the cable.
i also tried connecting my device to my brothers laptop.
correct me if im wrong, but when the usb fails to connect to any laptop, their should be a notification in the laptop that the device is not recognized. but in my condition, no notification shows up. its like my device does not really connect at all.
oh and if it helps, i bought an otg cable before it started malfunctioning. but the only thing i had conneceted to my device is a wired mouse and a wired generic gamepad, which both seems to be working perfectly fine.
also, if i connect my device to a wired mouse, it would work perfecly fine. i could also connect to a usb flash drive, that is via the otg cable.
so whats weird is that the usb cable does not work, but the otg cable works fine.
if you have any question or any suggestion , i would truly appreciate it.
Hmm.....well the good thing is the port itself isn't "dead" as you can still utilize it for OTG. My only suggestion is make a backup of all your apps and data and try a factory reset.

thank you for the suggestion guitarman2010. unfortunately my usb port isnt still working. i also reflashed my device's current firware. but still wasnt the solution i was looking for. i was just wondering if there is a directory under the root folder that holds the devices usb driver? would it be possible that the device's driver itself got deleted? i wam still at awe that the otg cable still works like a charm.
and another thing, is the male usb pin the same with the flash drive's pin? cause if i connect the usb cable to the otg cable it wont work, but the flash drive works normally.
sorry for the amount of question im posting
thank you very much for the suggestion. especially when u told me that the port itself wsnt dead. i can now breathe easier..
and future suggestion and advice would be appreciated.

Yesterday, I purchased an android 4.1 tablet and a tablet keyboard case for typing. I bought the keyboard because it had 2 usb ports in it. but unfortunately i am not able to use it. My tablet has a mini USB port where i can use a pendrive and even a 3g dongle via USB OTG cable. But when i connect it to the tablet keyboard it is not working. It is not showing anything, not even an error or any other message. PLease help me. How can i use the keyboard.
Hi,
i recently bought a Much i5 Android device with Android 4.2.1 preinstalled.
I also bought the Flirc IR Remote adapter which I connected on the USB OTG Port. First it worked fine, but a day later the device stopped to recognize any hardware keyboard on the USB OTG Port.
What's weird ist that it still regognizes Mice and Flash drives.
When I connect a keyboard I can still see it using the app "USB Host Controller" even the name of the keyboard.
Why is it not recognized by the system itself?
I have to mention that I changed the generic.kl under system/usr/keylayout to work with the Flirc keymapping. (I already set it back to stock, but that didn't change anything)
Also before this happened there was a option to enable or disable external keyboards in the keyboard selection menu of android.
I will reward the working solution with $10.
Thanks for your help.

Ok, I found a workaround:
I used the App "External Keyboard Helper" which recognises the keycodes from the external keyboard and gives me the option to remap the incoming keypresses.
Hello first sorry for my bad english, second i just got an older Asus Z380KL (runing Android 6.0.1 latest update from Asus) and its working fine for the most part. I just cant connect it to my PC (Windows 7/10) using USB. When i plug it in to my PC in device manager i dont see any new device but the Tablet is charging.
The tablet is in charging mode and i cant switch it to MTP. In Setting>Storage there is no option to change the USB mode, i dont get any notification in the pull down bar, in Developer menu i enabled USB debuging and tested the option to switch the USB configuration but if i change to MTP,PTP or RNDIS it always says Charging. I know the USB connector on the tablet is OK just tested my OTG cable and connected a mouse and it was working. Also i used 5 diferent USB cables that work when i try whit my Phone. Also tested all my USB2 and USB3 ports on my PC and laptop.
If anyone can help i wold be very grateful
Edit: Just tried it on Ubuntu 16.04 Live and MTP is working fine, Tablet connects i get the popup in the status bat saying i can pick if i want charging, MTP or PTP but on Windows 7/10 i cant get it to work its always in charging mode and i cant change it.
