[rt2x00-users] RT2800USB driver problem. txpower stuck at 0

[Vilius Palme]

Hello.

I'm having some sort of a problem with RT3070 usb dongle. It works
perfectly fine under 3.3.5 and 3.3.7 kernels, but somewhy refuses to
set txpower under 3.4.0. kernel .config is the same across all three.

Here's some output:

[root at R1 iw]# ifconfig wlan0 up
[root at R1 iw]# iwconfig wlan0
wlan0     IEEE 802.11bgn  ESSID:off/any
         Mode:Managed  Access Point: Not-Associated   Tx-Power=0 dBm
         Retry  long limit:7   RTS thr:off   Fragment thr:off

         Power Management:off

[root at R1 iw]# iwconfig wlan0 txpower 20

[root at R1 iw]# iwconfig wlan0 txpower 1
