Wacom Bamboo tablet in WinXP virtual machine.

I have a Wacom Bamboo tablet which I use in a VirtualBox WinXP virtual
machine for editing images with Photoshop. It has worked in Opensuse 10.2
and now works in 10.3 but I cannot get it working in 11.0. Windows claims
that the device is installed and working but I get absolutely no response
from either the mouse or the pen in 11.0. I have run into the same problem
using several recent versions of VirtualBox nonOSE and rightly or wrongly
have come to the conclusion that the problem lies with Opensuse but have no
idea for resolving it. Any suggestions would be greatly appreciated. I
can’t upgrade to 11.0 until I solve this problem.
