at76c50x-usb, the mac80211 port of at76_usb, has been merged mainline in
2.6.30, it works well on two at76c503a devices for me.

Performance and features are comparable (there were WPA patches[1] around,
CCMP for at76c505 devices only, but due to stability issues with the newer
firmware, they weren't merged in staging or at76c50x-usb); both drivers
sport an identical device coverage. The 802.11b chipsets themselves are
no longer in production, but were rather common (also in handhelds) around
6-9 years ago. In their current state, at76_usb and at76c50x-usb are
restricted to WEP64/ 128 or unencrypted networks and work equally well
(at76c50x-usb without the strange quirks that happen with at76_usb).
