Hi,
I'm detecting usb keyboards from shell using this simple script:
for i in /sys/class/input/input*; do
[ ! -f $i/device/bInterfaceClass -o ! -f $i/device/bInterfaceProtocol ] && continue
bInterfaceClass=$(cat $i/device/bInterfaceClass)
bInterfaceProtocol=$(cat $i/device/bInterfaceProtocol)
if [ "$bInterfaceClass" = "03" -a "$bInterfaceProtocol" = "01" ]; then
module=$(readlink $i/device/driver/module)
module=$(basename $module)
echo "found keyboard driven by $module"
fi
done
but for keyboards hidden behind logitech unifying receiver
there seem to be no such information in /sys.
Any ideas on how I can detect such keyboards via /sys or other
scriptable method?
(note that I'm interested only in "regular" keyboards, so single buttons
and some other devices are not interesting)
