Your device is in the current tables with the insertion patch date October 2011.
Unfortunately, I failed to Cc it to Stable, thus the patch was not backported to
3.2.7.
You could either choose to get a recent version of compat-wireless, or you can
echo "050d 2103" > /sys/bus/usb/drivers/rtl8192cu/new_id
(as root). That should bring the device to life.
