The attached file usbmon-working.out is the output when I pressed the 
backspace key. When I press any of the non working keys which is 
everything but the backspace and menu key. I don't get any output even 
when using 0u.

When attaching the keyboard I get 2 devices in
/sys/bus/usb/drivers/usbhid/2-1.1:1.0  and
/sys/bus/usb/drivers/usbhid/2-1.1:1.1

The output is in the attached lsusb.txt.
