that is the real problem. I never compiled in this new driver. After
enabling it the machine did some very weird things. It must be somekind
of luck that your system was still working. Mine doesn't. The problem is
that the ub driver don't contain the terminating braces for the device
id entries. You need to apply the following patch to get everything back
to normal.
