I have a LogiLink wireless USB adapter, kernel 2.6.29 (on ARM, ubuntu). Here is dmesg output:
[ 7872.506744] usb 2-1.3: new high speed USB device using musb_hdrc and address 3

In general the driver works.
I am measuring current draw and it is 400 mA. The adapter gets extremely hot. Changing txpower does absolutely nothing to the current draw (although when I type iwconfig wlan0 the settings appear changed). Setting 'iwconfig wlan0 power on' does nothing. I tried 'iwconfig wlan0 power period 1' - it does not work:
Error for wireless request "Set Power Management" (8B2C) :
invalid argument "1".
Apparently the driver thinks that it can change txpower, but it cannot :). Please help me to solve this problem. Is there any documentation available? Are there ways to debug wifi drivers? Thanks
i think this is just not implemented, apparently somewhere i read a lot is not implemented, and you shouldn't worry about it (was the gist of it).
besides, electronics are allowed to reach a heat of 80 degrees Celcius (as i read somewhere else)
