Comment (by anonymous):
another indication it's not working properly is when the USB card resets
or is being reconnected to the USB port the txpower on AR9331 radio resets
back to 18dBm:
txpower of both ifaces before resetting:
{{{

and config:

disabling USB port:
{{{

root@OpenWrt:~# iwconfig
gre0 no wireless extensions.
lo no wireless extensions.
gretap0 no wireless extensions.
wlan0 IEEE 802.11bgn Mode:Master Tx-Power=0 dBm
RTS thr:off Fragment thr:off
Power Management:off
eth0 no wireless extensions.
br-lan no wireless extensions.
}}}
and re-enabling reset txpower value of wlan0:
{{{
root@OpenWrt:~# echo 1 > /sys/class/gpio/gpio18/value
root@OpenWrt:~# iwconfig
gre0 no wireless extensions.
lo no wireless extensions.
gretap0 no wireless extensions.

wlan0 IEEE 802.11bgn Mode:Master Tx-Power=18 dBm
RTS thr:off Fragment thr:off
Power Management:off
eth0 no wireless extensions.
br-lan no wireless extensions.
}}}
i've repeat same procedure without any USB device and with card-reader
device plugged into USB port and the wlan0 txpower value remained at 0
