I use an USB-keyboard via an USB-switchbox on 2 computers (PC and Mac). When I boot into Windows or MacOS9 it doesn't matter whether my USB is connected, the keyboard gets recognized when the connection happens. Not so on Linux (PC), there the keyboard gets only recognized if it's connected during startup. If I forget to switch the keyboard to the PC before I start Linux, it isn't recognized and unusable. This is mostly annoying because I can't get rid of my AT-keyboard and just use the USB-keyboard, a none working keyboard is identical to a system crash! When the USB-keyboard is connected during startup everything is okay. I've seen this behavior with my Debian (sarge) system running my own built kernel 2.4.21 with USB input and keyboard drivers compiled in. I also see this problem when running Knoppix live CD, therefore it's common to any Debian based system, probably to any Linux system. Is this problem, not recognizing an USB-keyboard when not connected during startup, know and is there a solution for it? Is there a solution in the upcoming 2.6 kernel? If anyone wants to test this and has a desktop system with USB, just disconnect your normal keyboard, start the system and connect an USB-keyboard after the login prompt is shown. You could use the keyboard of a Mac if you don't have any. Also your kernel has to have USB-input/USB-HID and USB-keyboard support compiled in. O.
