Done. I rebooted after doing this, then plugged in the tablet.  I've
attached the output of dmesg from
just after plugging in the tablet, so that you can see the traceback
at the end. I've also attached a tar file
of the hid-uclogic.* files. Note that I did this with the latest
Ubuntu kernel (3.13.0-54-generic),
which is one version higher than the kernel that I tested with before.

Thank you,

Martin
