keyboards and evdev printing multiple keys

I am not sure this is a bug.
I have a Apple keyboard connected to a IOGear USB KVM.
I have installed evdev and the Xorg 1.5.3 server.
When I use any X apps the keyboard repeats three for one in. i.e. typing one 'L' puts three of them in the input. I noticed when looking at /proc/bus/input/devices there are three instanced of the keyboard.

Thanks for your help.

Does this also happen when KVM is not used?

Could you please verify with evtest on the respective device nodes in /dev/input/event* -- it will show us whether there are really three events coming out of the kernel, or whether it is X triplicating the keys.

This is an X server problem and the most likely cause is that your server is picking up a keyboard device (driver "kbd") and the evdev device separately. If you are using evdev 2.1, then you will get two events for each key press.

Another reason may be that you have an evdev device configured in the xorg.conf, and the same device gets added again through HAL.

Cheers,
Peter

I've tried commenting out all InputDevice sections in xorg.conf.
It seems to have worked so far. No "EE"s in Xorg.0.conf and my keyboard and mouse are working. Thanks!
