Anyway, for being able to understand both problems, we will need the dmesg output of the closest to upstream kernel you have. For the Wacom ISD bits, I am adding Jason to the thread. It looks like your device is an I2C over HID one, so I guess it did not worked before v3.11 or v3.12. In v3.16 I changed the way the Wacoms are handled and now they are all handled through HID. But this apparently broke your device, and I'll try to figure out what happened. We normally handle unknown Wacoms properly, but there must be something odd in your case that should hopefully show up in the dmesg output.
