After googling and scratching my head for quite a time I made some **real** progress. Now I have more things to research and find out.
To be more specific
> BTW,trying "iwconfig wlan1 power on timeout 10" failed,
Well , this is a problem with wireless-tools which has to do with parsing.
Using the latest v30 beta solved it - I did not got this error for "iwconfig wlan1 power on timeout 10"
(The error was , BTW
Error for wireless request "Set Power Management" (8B2C)
invalid argument 10).

Now, I ***do*** see messages the the driver is entering sleep and awaiting every 10
seconds. What I do **not** understand is why I don't see in a sniffer that the
wireless rt73 usb card sent null fames or frames with a proper PM bit set when it entered sleep state.
First I wonder what should be the case with rt73 usb device when in enters
sleep (power save mode) should it send null frames ? or should it send frames
with a proper PM bit ? I suppose this should be implemented in firmware am I right?
In fact, I see no frames sent from the wireless nic at all.AFAIK, it should inform the AP that it entered PS mode so
that the AP will start buffering packets for it. Isn't it so ? The only packets I see
is of the AP sending beacons. (the channel of the monitor wireless interface is 11 (this is a different NIC, not the rt73usb) , the same as the channel of the rt73 and of the AP.
Any ideas what could be the problem ?
