I believe what you're describing is a chip number made by Pulse (not an actual NIC). Does it have any other id like an FCC ID number? I cannot find anything from Pulse or by searching the number. Only folks selling the chip.

Legacy,
I think i may have found your driver (i was looking for the same one).
