byd driver is disabled by default in newer kernel versions, enable it by putting
echo -n "byd" > /sys/bus/serio/devices/serio1/protocol
to /etc/rc.local.
cat /etc/rc.local should give you following:
#!/bin/bash
echo -n "byd" > /sys/bus/serio/devices/serio1/protocol
Make sure the script is executable.
