Please try to create a monitor interface on the rt73usb AP after setting it up:

# iw dev wlan0 interface add mon0 type monitor

and run a tcpdump on that (with XX:...:XX replaced by the MAC address of
your client):

# tcpdump -i mon0 "ether src XX:XX:XX:XX:XX:XX"

Do you see any frames from your specific client?
