Keeping it short: I've followed all the instructions on

http://wireless.kernel.org/en/users/Drivers/ath9k_htc

in order to get the TL-WN721N USB WiFi device to work. I tried with 

2.6.37
2.6.37.1
2.6.38-rc6 mainline last stable

in all permutations with

linux-next compat-wireless
linux-2.6-allstable compat-wireless

in turn in all permutations with the firmware for the Ar9271

from the Kernel GIT
from wireless.kernel.org:
http://wireless.kernel.org/en/users/Drivers/ath9k_htc?action=AttachFile&do=view&target=ar9271.fw

Nothing helped. The best results I got, and where I am currently stuck
is with

2.6.38-rc6, linux-next compat-wireless, firmware from GIT

When I boot (Gentoo), everything starts okay, but I get constant

"try 1"
"try 2"
"try 3"
"authentication timed out"

in dmesg. When I restart /etc/init.d/net.wlan1 I get, after
wpa_supplicant is said to start

SIOCSIFFLAGS: Unknown error 132
SIOCSIFFLAGS: Unknown error 132

wpa_cli can subsequently not connect to wpa_supplicant. I'm clueless,
what else can I do? Why is it not working? on wireless.kernel.org the
chipset and the device I own are said to work!
