is there more information available? datasheets? drivers?

NAK. you cannot change device IDs currently used to some new code.
this will break most eGalax setups as the device ID 0x0eef,0x0001 is used
in most of them, including the one i have..

you'll need to find a way to distinguish the screens. as a starting point
i attached an lsusb -vvv output from my screen...
