Same here; someone at $work bought couple of these teeny dongles.  I've
applied small id patch (attached), and tried to use it (it reportedly
works flawlessly under Linux using this [*] driver).  I could load the
module, but MAC address was clearly bogus (00:00:30:34:43:30); yet I've
created wlan0 just to find out that there is no list scan results, and
wpa_supplicant(8) gives me this in an endless loop (GENERIC kernel, so
I presume all wlan-related stuff should be in place):

   Successfully initialized wpa_supplicant
   ioctl[SIOCS80211, op=103, val=0, arg_len=128]: Device not configured
   wlan0: Failed to initiate AP scan

This is on relatively fresh 11-CURRENT as of Oct 18th, i386.  Any clues?
It would be nice to get more of these little guys to work, esp. there is
working Linux driver available for reference.
