[Q] USB OTG Keyboard Problem - $ for working solution - General Questions and Answers

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.
Regards
Fleischmann

Solved
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.

[Q] USB port

Is the main USB port active or any good uses for it yet
USB thumbdrives appear to be the only thing that works and are not hot-swappable (must reboot to see it). On some very rare occasions the thumbdrive will be seen without a reboot, but the ratio is about 1/20 times (yes I tested this).
USB host function and bluetooth input connectivity are very poor on the stock based FW.

I've gotten a wireless and wired keyboard to work, but never a mouse.

Both stock and TnT Lite worked with the keyboards. I've tried USB wired and USB wireless; keyboards work, but no love for a mouse. Haven't tried Bluetooth

Few questions please:
1. Are you using TnT Lite 2.0?
2. This device really has USB wireless drivers and control chip, or do you mean bluetooth?
3. How can you get a wireless or manual keyvboard to read when the options will not allow anything but the default keyboard? This is the (or a) reason Wiimote and other input devices will not work.
4. What keyboards for USB and wireless?
I could not get the device with TnT 2.0 to see anything via USB except thumb drives and absolutely nothing is seen via bluetooth as far as input devices. Part of the problem is the same process for hotswap (that does not work) is also part of the polling process for hardware to be seen and read. Gtablet apparently does not look for devices except at start-up.
Thanks
any extra steps needed other than plugging it into the usb port....?
what model keyboards were they?
I have found that it is also good for charging my phone. Seems to work whether the screen is on or off.

I just plugged my generic wired keyboard into the USB port -- first times after the g-tablet was booted up, the second time before it was booted up -- both times the keyboard works just fine. To enter type I simply tap on the text input box and start typing on the real keyboard. If you tap on the textbox you will bring up the on-screen keyboard; that does not interfere with the real keyboard. Alternatively, you can touch the "return" button which will remove the on-screen keyboard, at which point you can then start typing with the real keyboard without the on-screen one, the one exception being the default brower (the on-screen keyboard reappears as soon as I start typing).
Right now I'm on TnT Lite 2.0, but the USB keyboard worked when I was still on stock (pre-update).
As for USB flash drive: I just plug mine into the already booted-up g-tablet, and I am able to access all the files -- I can view the pdf and listen to mp3 etc (this is definitely not true with stock TnT).
NOTE: ESfile explorer do NOT see the files on the USB drive the moment I plug the drive it. So I back out to the home screen, hit ESfile explorer again, and wa la, the files are there. I guess it takes a few seconds to scan the drive (understandable...)
I just rebooted the g-tablet and then plug in the USB drive, and it still works! This time I waited 5 seconds before firing up the ESfile explorer and the files are there.
I have no luck using a wired mouse with the g-table
I have used BT keyboard with Bluetooth keyboard app, but as has been confirmed, BT mouse does not work with bluetooth apps or dirctly. The BT program was problematic, but a generic belkin bt dongle works with the wireless keyboard just by pushing the pairing button on the dongle and then just hitting some random keys on the keyboard while it is in discover mode. After that, you just begin typing.
omg wooooooo quake 3 with keyboard hahaha this is a riot
Whatformat does the drive have to be in for the USB to read it. Also im running latest version tnt lite and the device seems to hang alot. I have a task mgr and fequetly close apps and it helps some. Any ideas? Seems alot of stuff starts up when you boot. Is there a way to stop that?
thanks Matt
Also my Microsoft bt kb and and mouse work fine on this device. Haven't tested the bt pocket kb for my old dell axim yet. Needs batteries.

I'm using TnT lite 2.02. I've tried a standard USB keyboard and it works fine. Takes just a few moments for detection, but afterwards tapping into any edit box allows for input via the keyboard. For wireless, I've tried several RF wireless combo units. These, from Microsoft, Logitech and a few others, have a USB transiever (sp?) That works with the keyboard, but I haven't had any luck with a mouse.
My unit seems to play nicely win USB flash drives as well, including being hot swapable friendly. I've not had to reboot just for detection of a flash drive.
They only Bluetooth device I've tried is a pair of Motorola S9 stereo headphones, which worked just as well as they do with my iPhone.

Is your device newer? As in last week or two (mine is one of the first 1,000)? No luck with mine to the point I returned it yesterday, a few days before too late to return it. I tried everything I could think of with no luck.
What was the keyboard model & number? Zero luck with bluetooth as well, for any input device I tried. Using the same FW as you are.
I use my lenovo htpc kb/mouse. http://www.amazon.com/Lenovo-Multimedia-Remote-with-Keyboard/dp/B0036VO67I
As soon as I plug it in it works. A mouse cursor pops up when it detects the slightest movement of the trackball.
Again, this is wireless not BT on CM B4.

Sorry, I am referring to TnT based FW. With CM you lose either the internal or external microsd (one or the other).
Of course CM works, since no lame TnT OEM devs to screw things up that should not be messed with in the first place
If CM ever works with all storage, it will be a nice option
People report success with TnT 2.0, but not seeing any specifics as to how and what they are using. Nothing worked for me using TnT 2.0.
I have used a thumbdrive with good results. I usually put the tablet to sleep while swapping the usb drive in or out. This accomplishes two things...one, it keeps the tablet from spontaneously rebooting (which happened to me once while pulling out the thumb drive) and two, it ensures that the tablet sees the the usb drive. The tablet seems to scan for drives when it wakes up.
On my tab with CM B4 \sdcard is my 8gb micro sd (external card) and \emmc is the onboard 16gb of space. It still doesn't go into usb storage mode when plugged into a PC but you can adb in or go to CW and mount usb. I'm pretty sure Bekit integrated the fixes that came down with the TnT update, not to mention more that we found. Huge thanks to him for all his hard work and quick updates.

[Q] USB Mouse and Keyboard

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?

[SOLVED] I enabled storage encryption and now the virtual keyboard does not popup

I don't have a OTG cable at the moment out else I would try a keyboard. I have long pressed and tapped on everything. Ideas?
I was using rooted stock 4.1.2 and Swype keyboard. I have searched the forum to no avail.
I just got a new USB OTG host cable. I plugged in a keyboard and viola! Now I have unencrypted the device and all is happy.

USB keyboard problem

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!

Realme 4k stick - OTG USB keyboard not working

Hi guys.
Just bought a Realme 4k stick with google tv.
I used to have an android 7 tv box with mouse and keyboard.
For some reason on google tv the mouse and keyboard does not work properly.
When I go to settings it expects keyboards moves so if I click on mouse it always click on the first option.
On netflix app I canĀ“t choose the profile on mouse, the same problem, it expects some keyboard left right, not a mouse click.
At my old android 7 tv box, the mouse right button was a back key on menu. All worked well with this setup of back and forth...
anybody succeeded using external usb mouse/keyboard?
Hi there do you solve problem? I cant even use any keyboard and Mouse not even extra usb drive to watch photos etc. What kind of hub do you use? I have a hub with external power delivery where i connect power charge then connect micro usb to stick all works but when I connect any external (Mouse, kboard, usb drive) nothing happens.
