Are you sure of this? Those are differential outputs, not USB outputs.
Looks to me like these chips need to be paired with another baseband
processing chip. This is half of a two chip wifi solution.  There is a
kernel driver for these chips when paired with the W89C35D.
drivers/staging/winbond.  W89C35D is the needed USB to WLAN interface
chip.

The Ralink chips are single chip solutions with USB output.
