I'm using the rt2800usb module for the Buffalo WLI-UC-GNM using ad-hoc mode.

T:  Bus=01 Lev=02 Prnt=02 Port=01 Cnt=01 Dev#=  3 Spd=480  MxCh= 0
D:  Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
P:  Vendor=0411 ProdID=01a2 Rev= 1.01
S:  Manufacturer=Ralink
S:  Product=802.11 n WLAN

It works ok, but after idling for a while, it does not response, and
module needs to unloaded and modprobe again to make it work.

The same mac80211 and cfg80211 works for iwlagn and no problem with
idling timeout.

Is there any parameter to control the rt2800usb to make turn off power saving?

I've tried "iwconfig lwan0 power timeout 0 power off" but no effect.

Linux 3.1.0-rc3 with commit caca9510ff4e5d842c0589110243d60927836222.

Thanks,
Jeff.
