Sorry about the delay.

It seems that the options are limited. The HID needs to be made of two 
parts, vendor ID and part ID.

For the vendor ID, you may use the PNP ID (RTL) or the PCI ID (10EC).

For the part ID, you are limited to 4 hex-digits. I didn't get any 
positive answers on how to support '1015P', the only solution seems to 
be to create a new part number, or detect at run-time which of the 
'1015' skews is actually used.
