Well, while I do have extra machines, none of them run MS, so that's no
help for me.  Kai Wang gave me an extremely nice kernel module, he's named
it krepdump, and it's made a really remarkable report.  I think I will cut
and paste it here, it's obviously full of info, but I don't yet really know
how to interpret it.  I mailed a better description of the tablet to Kai
separately (and also to the usb list), maybe that info might be of help in
making sense of this:

What follows is all from my dmesg.
