The microcontroller is 89C52 (set in the panel, 
1st photo), compatible with 8051 series.
Memory (2 chips) is to the left, and the flash 
rom seems to be the chip with the largest number 
of the pins, more to the left.

Seems like you'll have to acquire the usb dumps 
corresponding to the various phases of work of 
your device, and either analyse them for 
replication in sane driver yourself, or pass 
them to the experienced guys in this list. :)
