Well, you can always unbind interface 0 from usbhid -- it corresponds
to the 2-1.1:1.0 file in /sys/bus/usb/drivers/usbhid/. If you do that,
you'll probably find the few keys which _do_ currently work suddenly
stop working.
But there's nothing to be done immediately about interface 1; usbhid is
_already_ using it. It just isn't using it correctly.
Adi,
could you please provide output of
cat /syse/kernel/debug/hid/<keyboard>/rdesc
anytime after the keyboard has been plugged, and
in /sys/kernel/debug/hid I have two devices for the keyboard. One is
0003:060B:0230.0002 and the other 0003:060B:0230.0003
attached are the rdesc files for both devices.
cat /syse/kernel/debug/hid/<keyboard>/events
> from the time you press any of the working and non-working keys? (both

I only get events for the working keys on the *:0002 device.
All other files were empty after I pressed some keys.
The events for the working keys are attached in the *.events file.
I first pressed backspace and then the menu key.
Hi Adi,
I'm not sure about my patch below because of interface one, maybe you
can give it a try.
What kernel version do I need? I'm running Ubuntu 10.04, so can I apply
this to a 2.6.32 Ubuntu kernel or do I need a current 2.6.39?
Any ideas if I'll run into problems if I run Ubuntu 10.04 on a 2.6.39
kernel.
Cheers
Adi
