Hi Mike.  The suspected Zydas firmware issue has to do with beaconing
but I am not sure if you're seeing the same problem.  In the issue
that we see, the device seems to stall and stop responding to USB (in
this case, the USB communication in the driver times out).

There are currently no other USB devices supported except for the
Marvell '8388 with "thin" firmware (available on OLPC XO-1 laptops).
However I have been working on adding support for the Ralink USB
chipsets (rt73usb via the rt2x00 driver), though that's not working
yet.  If you're using the latest wireless-testing kernel and would
like to help, my initial patch is here:

Thanks,

  -Andrey
