Adi,
could you please provide output of
cat /syse/kernel/debug/hid/<keyboard>/rdesc
anytime after the keyboard has been plugged, and
cat /syse/kernel/debug/hid/<keyboard>/events
from the time you press any of the working and non-working keys? (both
cases will be interesting).
Oh, and the above assumes that you have debugfs mounted under
/sys/kernel/debug.
Thanks,
