                simple instructions - insert dongle first pls
                $ sudo ifconfig eth0 down # cable can remain connected
                $ tce-load -i wifi rtl8188eu
                $ sudo wifi.sh # and follow prompts

                For module parameters, ids etc $ modinfo 8188eu 

                If you need power, managed mode etc
                see README.txt in /usr/local/share/doc/8188eu dir
                Those commands will need more TCEs downloaded and installed
