I want to simultaneously use a PS/2 keyboard (This is a laptop, so
switching that out is not an option) and a USB numeric keypad, which
works perfectly as a usb HID keyboard. Is there any way to do this
with the current keyboard driver ?

Should work just fine today. What kind of problems do you have when you
try to do it?
thanks,

Just not getting any events from the keypad. When I load up evdev, and
cat the device I get the appropriate gibberish, so the device is
detected okay. This is 2.4.18, if that makes a difference for the
purposes of this discussion.

If the device is detected, how is it detected? Is the USB HID driver
binding to the device?

Looks good to me (from a USB subsystem standpoint.) As for why it's not
working for you, I don't know. Perhaps it's spitting out keycodes that
you're not expecting to see.
Good luck,

OK, evdev is on the userspace side of the input core (and USB is on the other).
If evdev reports events (and you can decode them, if you are interested, using
tools available from the linuxconsole CVS), then all is probably well with USB and
the input core.
The obvious error would be not compiling in the input layer keyboard driver (or
not loading the module, whatever).
If that definately isn't wrong (like lsmod shows the module, or a normal USB
keyboard works fine and the keypad doesn't), then we'll likely need the
HID descriptors. Probably easiest to get them from evdev using the evtest
tool from linuxconsole CVS.

Good call. That did it, thanks.
