The evidence points to some kind of Broadcom chip. The USB data base says that 
an ID of "0846:9020" is a "WNA3100(v1) Wireless-N 300 [Broadcom BCM43231]". In 
addition, the Windows driver name of bcmwlhigh6 indicates a BroadCoM WL driver 
of some sort. Given the relatively small amount of initialization traffic, it 
must be a fullmac device that likely does not need external firmware.

I remember seeing some mail about the Broadcom guys working on a Linux driver 
for a USB fullmac device. Is this the one? (I added Arend to the Cc.)
