live: use a different product ID than 0x0001

This seems to be wrong

I wonder what the effects are of using the actual PID for this device, at least on the intuos pro. We'd have to send a different stylus ID through though

For the Intuos Pro, it could be OK, though we are using a Bluetooth connection and not a USB one. So theoretically, nothing prevents Wacom to reuse this PID in a different Bluetooth product. However, given that Wacom is now using the report descriptors in Linux, we should be fine reusing any PID which doesn't have a special treatment in the wacom.ko module.

The only problem with 0001 is that if we keep the same PID for all versions, libwacom might be confused. Ideally, we should assign one PID per product, or make libwacom matching on something else.
