[clug] how to configure a second keyboard

[Eyal Lebedinsky]

Andrew

A simple script can search for the device:

for f in /sys/bus/usb/devices/*/idVendor ; do
	d="`dirname $f`"
	test "04b4:0100" = "`cat $f`:`cat $d/idProduct`" && \
		echo `basename $d`
done

Which says:
	7-3.1.4
and I should now be able to pick the correct /dev/input devices.


But the main question remains: how do I configure this keyboard differently
than the main one?
