Hello.

I have upgraded kernel from version 2.6.16.12 to 2.6.17.4,
and my tablet does not work since then.
The tablet device (/dev/input/event2) is present and
can be opened, but wacdump do not show any events.

Now I'am using new kernel with the old driver, and
it seems to work fine.

"lsusb -v" output is in the attachment.

Thanks.
