Hi list,

After having upgraded my computer to Slackware 13.0, I'm trying to get my Wacom
Bamboo tablet working again. (It was working fine on Slackware 12.2, BTW.)

So far, I have installed the wacom software through Slackbuilds.org (it's
version 0.8.3_6), and from the looks of it, everything should work fine. But it
doesn't...

/proc/bus/usb/devices shows the following:

T:  Bus=03 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#=  2 Spd=12  MxCh= 0

E:  Ad=81(I) Atr=03(Int.) MxPS=   9 Ivl=4ms

/var/log/messages:

I've created a udev rules file (as per the instructions in the HOWTO), so that a
symlink is automatically created:

root@darkstar:~ # ll /dev/input/wacom
lrwxrwxrwx 1 root root 6 2009-10-26 12:16 /dev/input/wacom -> event4

Running wacdump /dev/input/wacom shows the following:

This still looks ok. It seems that the system detects the Wacom Bamboo tablet.
However, when I now move the pen around the tablet, or press any of the buttons,
nothing happens.

Similarly, 'xxd /dev/input/wacom' and 'xxd /dev/input/mouse2' don't do anything.
(According to /dev/input/by-id, mouse2 is the Wacom mouse device.)

I haven't configured anything in /etc/x11/xorg.conf, X is configured
automatically. This is what /var/log/Xorg.0.log has to say about the device:

To me, everything looks fine here. But nothing actually happens when I move the
pen around the tablet.

Does anyone have an idea what might be wrong here? It would sure be nice to have
a working tablet... :-(

Thanks for any tips and pointers.
