What i want to happen is that, everytime i'll use my usb keyboard automatically my internal keyboard will disabale..

Your best bet is manually (see last paragraph). If you have coding skills, you can do these ideas, though they are not simple:
Use an always-running Batch or PowerShell script to interface with devcon.exe.
Write a driver or low-level utility to do it yourself.
If not, you should disable it manually using Device Manager (devmgmt.msc). You'll want to check under Human Interface Devices, and disable (or enable) the keyboard that's always there.

I have an unusual exploratory test automation task, which relies on detecting keyboard input. (certain trigger words).
However, to automate the task, has proven very difficult, as the input must pass through the keyboard driver it seems. Thus, setting UI automation (like Sikuli, or even ghost mouse) to click on the on-screen keyboard, OR using Sikuli to 'type' or copy/paste text into any windows UI, is not registered.
Any ideas of how to emulate physical keyboard input for the purpose of automation?
You could use an Arduino to emulate a physical keyboard (there are easy to use libraries available). Also, if you use one of the more capable Arduino's with multiple serial ports you can send it what keypresses to emulate through the serial port. The computer will think it is a keyboard like any other. Except you can control it with software.
Of course, this solution assumes you can connect something to the USB port of the test computer.
I have a headless Debian ARM machine that I'm running Node on. The device has hard buttons that are mapped to normal keyboard events using gpio-keys.
My goal is to capture the global events from both the hard buttons as well as any attached keyboards in Node. I need a solution that can capture the keydown/keyup events independently of the terminal that it's run in (it will be run over an SSH session). It doesn't have to be cross-platform, as long as it works on ARM Debian I'll accept it.
I am imagining something reading directly from whatever sysfs attributes are necessary, but that's not a requirement.
Can anyone help me on this? I've been stuck for a while.
One of the device files /dev/input/event* will represent the gpio-keys device. You can figure out which one in a number of ways; one easy one is to look at the contents of the uevent file for the device, e.g. /sys/class/input/event0/device/uevent. It'll contain a number of useful key-value properties.
Once you've figured out which device you want, you can open and read from it. It'll return a stream of struct input_events, as defined in <linux/input.h>. These events will correspond to presses and releases for each of your buttons.
You may also want to take a look for existing solutions for at least part of the problem, such as node-keyboard: https://github.com/Bornholm/node-keyboard
I'd like some way to send keyboard input to a linux machine without a keyboard. I'd like this input to be accepted in any linux console, and in xmbc.
One idea I had would be to write some type of virtual USB keyboard that would send the input to in that way, but maybe this is over complicating it.
Basically what I'm looking for is Synergy without X (and with XMBC)
Anyone have suggestions on where to look?
You could write a user space driver to inject events into kernel.. so you can ssh into your linux box, run the driver and inject the keypresses you type.. so it will be as if there is a physical keyboard attached and would work with all programs. This gives good info on how to write user space drivers... if you don't want to reinvent the wheel, this program TermKeyboard does exactly that.
Disclaimer: I wrote the program
there is a keyboard for fbcon on sourceforge. to com;ile it you must add string.h include

We have a kiosk application that runs matchbox on top of linux, and has only a barcode scanner for input (no keyboard). It would be great to be able to print a barcode that--when scanned--sent commands like SysRq R etc, so that one could REISUB without having to disassemble the unit.
If there is not an existing way, could you patch the barcode driver to interpret a certain set of symbols and initiate the sequence?
Why do you need SysRq? Is the machine actually wedging itself or are you just trying to reboot cleanly? Why not just put a "reboot" command into whatever protocol you're using? What's wrong with simply doing a hard power cycle?
I want to be able to intercept (and do arbitrary processing on) auto-repeating key presses on Windows. I'd like to know how keyboard auto-repeat is implemented so that I know what options I have. i.e. can I intercept at the:
application,
device driver and/or
hardware level
?
Update: It looks like auto-repeat is (poorly?) generated at the hardware level and then overridden by device drivers (see here).
To modify or filter behavior, you can intercept keys using a hook:
SetWindowsHookEx using WH_KEYBOARD
The hook procedure receives, among others, the repeat count (due to holding down the key)
Note that the low level keyboard hook (WH_KEYBOARD_LL) does not receive the repeat count.
If all your windows are created in the same trhead, you can use a thread-specific hook, and avoid moving the hook procedure to a DLL.
I dimly remember that repeat counts are generated by the keyboard itself and the LL hook sends repeated keydown events - I may be mistaken, though. Under DOS, the key repeat rate and time that was set in BIOS or through a BIOS call did return to default values when a DIN or PS/2 keyboard was unplugged and replugged. I am not sure WHY you need to know exactly.
I suggest that you might want to edit your question... your actual question is "How to suppress auto-repeat on Windows in ${yourLangauge}"...
To which my response is, I haven't got a clue, I've only ever done it in assembler (MASM 80286)... and even then I found a solution on a BBS (does anyone remember them) and just used it. From memory, the intercept has to be done at the device-driver level.
The implementation of autorepeat ($100 says it's assembler) problably won't shed any light on supressing it... that and Microsoft plays those cards very close to it's chest.
Cheers. Keith.
EDIT: I've just thought... techniques may now differ between versions of windows and the plethora of various devices... Oh goodie!
Sounds likes this is "Not programming related", however.
Go to "Accessibility Options" in control panel.
Select "Settings" under "Filter Keys" group, in here, you can switch off repeating keys for that user on that machine.
Hope this is what your looking for.
P.S. Above instructions given for Windows XP.
