There is at76c50x-usb (using mac80211) and at76_usb in staging (which is going away sometime in the future). Because at76c50x-usb is the path forward, I will omit at76_usb here. > however when trying to use WPA with the chip the association > conversation fails.

The answer is (b). At least some chipsets seem to support WPA. I'm busy with other projects right now and I don't have time to implement WPA support, but I can give you hints. I see two ways forward: 1) use mac80211 to encrypt the frames Currently encryption happens in hardware, but also mac80211 can do it. And mac80211 sw encryption supports TKIP and AES, so with luck you will get WPA working with that method. Remove .set_key from at76_ops and see what happens. 2) enable firmware support for WPA Milan Plzik had some patches for at76_usb which added WPA firmware support. The patches are here: http://git.kernel.org/?p=linux/kernel/git/linville/wireless-legacy.git;a=shortlog;h=at76 You can port them for at76c50x-usb and get WPA working. First check that the WPA firmware supports your device, though. If you need any help, send email to me and this list.
