Excellent, if no one send patches I guess I will.

So we have a page for this now:

http://wireless.kernel.org/en/users/Drivers/otus

Init you can find a list of devices. Let me just paste what we have
there now:

Dlink

    * DWA-160A1 

Netgear

    * WNDA3100
    * WN111v2 

TP-Link

    * TL-WN821N 

AVM

    * FRITZ!WLAN N USB Stick (USB ID 0x57c, 0x8401)

Thanks! BTW if you add a kconfig option for it please point users with
this info:

This driver requires its own supplicant driver for
wpa_supplicant 0.4.8. For your convenience you can find
the tarball here:

http://www.kernel.org/pub/linux/kernel/people/mcgrof/otus/wpa_supplicant-0.4.8_otus.tar.bz2

Before compiling wpa_supplicant, ensure your .config has atleast the
following

CONFIG_WIRELESS_EXTENSION=y
CONFIG_EAP_WSC=y
CONFIG_WSC_IE=y
CONFIG_DRIVER_WEXT=y
CONFIG_DRIVER_OTUS=y

After a successful compile, you can use the device with wpa_supplicant
as follows:

wpa_supplicant -Dotus -i <atheros device from ifconfig> -c /path/to/wpa_supplicant.conf -d
