                simple instructions 
                Optional dependency- wireless-db read its info please

                $ sudo ifconfig eth0 down # cable can remain connected
                $ tce-load -i wifi rtl8188eu
                $ sudo wifi.sh # and follow prompts

                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
                                
                dmesg now outputs a lot more info.
