Comment 29 for bug 234466

I have manually compiled and installed linuxwacom 0.8.3-3 in the hope of getting this fixed. I think it happens less often now, but it may just be coincidence.

I can usually fix the tablet by running a script containing this:

echo -x "\x00" > /dev/ttyS0
sleep 0.5
echo -x "\x02" > /dev/ttyS0

The pen becomes slower than "normal", but is still usable (unlike when sending \x03).
