I hope I have given enough information on trying to troubleshoot this.
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.
