hmm... an overflow here.

It's probably timing issue as well.

hmm... what does lsusb -v -d 057c:6201 reports to you ?

Did you try setting the parameters by hand ?

# iwconfig wlan0 essid <ESSID> key <KEY>

and then

# dhclient wlan0

It's probably affected by timing as well. That driver sure needs some
rework. Btw, are you using the mac80211 version or the other one ?
