My card is UB91, so you means I should update to this one(ar9271.fw) blew:

http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=blob;f=ar9271.fw;h=0ec953b404c1912dc64fa3b0171cffae82b0f375;hb=8f919160792e4702c6b7a67a243cea4f757407e4

This one still can't prevent the probe failure...

Any suggestions?

thanks,
