[Bug 597123] Re: wacom kernel driver ends up in non-working state after first unplug

[Tim Cole]

The Xorg side of things seems to be working okay (and we've proven that
the problem is on the kernel side using evtest above), so all that
should really be necessary to check for the existence of the bug is the
following:

1) with the tablet plugged in (the first time), run `xinput list` to find out the tablet's device ID (look for the entry without "eraser" or "cursor")
2) run `xinput test ID`, where ID is the ID from 
3) observe that scribbling on the tablet generates input events
4) unplug the tablet
5) observe that `xinput list` no longer lists the tablet
6) plug it back in 
7) observe that the tablet is back with `xinput list` (normally it will get the same ID again, but check)
8) run `xinput test ID` again, and observe that scribbling on the tablet no longer generates events
