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):

  The problem occurs on ARM PDA (hp ipaq h5550), Familiar linux with
standard handhelds.org kernel (I don't have informations about applied
patches). Informations from driver:

  If anyone knows what could be the problem, please let me know. I would
like also try actual snapshot, but I have not yet managed to get
cross-compilation environment to work successfully enough for kernel
module compilation.
