2 usb keyboards connected to a normal x86
One keyboard working as usual in xorg, but I need that the other one doesn't send anything to xorg but instead I want to process its keystrokes with some kind of background process.
First a bit of theory: you communicate with a UNIX system by using a "tty": a "terminal" consisting of a keyboard and a screen, usually connected via a serial line.
If you connect to a UNIX system over a network you use a so-called "terminal emulator program" (many times "xterm", but that is not the only one) to emulate such a terminal and its serial connection is emulated via the network connection.
There is a special form of a tty, which is called console. This is not connected via the standard serial line but directly attached to the computer. Perhaps the local screen attached to your VGA-card and the (first) keyboard form this console.
Now, after that much theory, to your specific question: this might work, but not necessarily with a USB-attached keyboard and definitely not with a background process. Background processes are part of a process hierarchy, headed by some foreground process: this is usually the shell from which you initiated the background process, typically by issuing the command:
Since the shell you typed that in was already connected to some tty (the one which keyboard you used to type it, probably the console) the background process inherited this connection. You can cut it off from this (by using the nohup command) but per default itis attached to the one you used to call it. Furthermore, a single USB-attached keyboard is not a terminal.
