Okay, then turn on debugging. We could need LBS_DEB_HEX, 
LBS_DEB_ENTER, LBS_DEB_CMD, maybe LBS_DEB_HOST, maybe 
LBS_DEB_SCAN, depending on your actual problem.

Look at http://wireless.kernel.org/en/users/Drivers/libertas for 
a reference to lbsdebug, which allows you to turn this on and 
off at will. You can also fiddle with hex values, e.g.

  echo  2113537 >/sys/module/libertas/parameters/libertas_debug

Search the mailing list archive for "claud_yu"'s problem, his 
problem might have been simular to yours.



For your reference, here's a valid scan command and response, to 
a 5.0.16p0 firmware:

Hehe, if that solves your problem you owe me a webcam :-)
