I meant a plain 3.18 (you need a 3.17 at least to have the device handled by hid and 3.18 to have wacom picked up when your device shows up). Or, you can also just use the wacom out-of-the-tree driver, without my patch to support the bamboo pad. > > Sorry, I don't have my tablet with me right now but I'll mail you the > recorded data to you this afteenoon.

I am actually more interested in the description of the device, but having some events will help too.
