I just got a das keyboard today, got it plugged in to my computer... and nothing.
Literally, nothing, nothing at all happened. No "Device Not Recognized;" no New Hardware Detected wizard, not even the usual "Da-dum!" sound I get when I plug in any hardware. I tried it with and without the cable that comes with it (it has a Y cable for USB, it says to try that if the keyboard doesn't work when you plug it in).
Strangely, both the keyboard and USB ports work just fine--but not in Windows. I can fool around in my BIOS just fine with it, and the same holds true for GRUB and Linux. I think this is something I might have inadvertently caused in the past, though. I have quite a few services that I'd never used disabled, but at the same time, I don't think that's the issue, any services that "make sense" to me to have running are running, those being HID Input Service, Plug and Play, and Shell Hardware Detection (although, I don't think this does much for keyboards).
It's worthy of note that when I plug the keyboard in and have Device Manager open, I can see it refresh, as if reacting to a change, but nothing on the list changes, not under Unknown Devices nor Keyboards, HID
In short: I'd like to know how to fix this issue: I plug in a keyboard, it is not recognized. The keyboard works, the USB port works, the OS works with different keyboards. No notification of failure of success is given when it's plugged in.
I'm plugging the keyboard directly into the USB ports on the motherboard, which is an ASUS P4P800-E Deluxe. I'm running Windows XP MCE SP3
