As I have understood, reading Poduct ID register (together with reading
checksum register) is primarily for check integrity of uploaded FW.

With that RF tuner IC, Linux driver and public available FW for XC5000C
(from Kernel Labs) I successfully received analog and digital transmissions
over an air. Didn't checked it with DVC-C though.
