Hello,
unlike the HID driver in Linux 2.4, the HID driver in Linux 2.6
blacklists some USB devices like the Aiptek 6000U/8000U tablet,
apparently in favour of the Aiptek driver now included.
Sadly, because of that it isn't possible any more to run the tablet
using the HID driver (it's working fine with HID in relative positioning
mode).
Because I only need relative positioning, I'm completely satisfied with
HID, I don't need an extra module doing the same job.
To get it working again, I made a simple patch which allows the user to
disable the ignore blacklist using a module parameter.

can be disabled using modprobe hid useblacklist=0
