If you mean "RX EAPOL - hexdump" from wpa_supplicant, it does not
include Ethernet header, so the ethertype (0x888e) is not included in

I have never used Atmel driver (neither for pcmcia nor usb), so I do not
know for sure what could be happening here. By the way, is this driver
with WPA support and wpa_supplicant driver interface code available

Some comments about the USB log:

Did you set the wireless interface UP at some point? If not, this could
explain why EAPOL frames are not received..

For some reason, the driver does not seem to like many of the scan
requests. This may or may not generate some issues.. Anyway, at least it
looks like the card is able to associate with the AP.
