Scanning results while not associated

  Hello,

  I would like to ask if it is possible to get any scanning results when
the wifi adapter is not associated. Scanning with unassociated card
always returns:

wlan0     Interface doesn't support scanning : Device or resource busy

  when I enable debugging, it seems that the card permanently scans for
the networks and attempts to associate (but this fails because of
missing WEP key). I can even see name of my network in logs, but still,
scanning using wext/wireless-tools just doesn't work. Dmesg output
follows (homenet is my local network; output repeats many times):

  Sorry, I absolutely forgot to mention these informations. The first
version I have tried is 0.12beta23, then I also tried CVS snapshot from
20060601 - both behaved the same way.

Re: Scanning results while not associated

You should use 2.4 branch of at76c503a. Please report your problem to
at76c504a-devel mailing list.
