Hi,
I've got a Chicony KU-0108 USB keyboard with some multimedial keys: most of
them works fine, but there is no chance to use the 'cut', 'copy' and 'paste'
keys with the official kernels: the problem is that the keyboard reports
strange usages for those keys, so I write a little patch that fixes the bug.
This patch (against 2.6.6) modifies the hidinput_configure_usage function in
drivers/usb/input/hid-input.c: it checks for the usages reported by the
keyboard and fixes the values so that they can be seen as "standard" keys.
Comments are appreciated
[I've subscribed only linux-usb-devel, so plese CC replies from linux-kernel]
cheers,
Antonio
