Odd, yeah that should work, TL-WN721N is listed as AR9271 and not
AR7010, which ath9k_htc also supports. The AR7010 devices does require
an update usb mode switch [1] but since your device is not AR7010 I do
not think that is the issue here. I take it you are usng
compat-wireless?

CC'ing the Ubuntu kernel team. Hey you guys have any idea on this?
