              After usb dongle is inserted 
              $ sudo ifconfig eth0 down # cable can remain connected
              $ tce-load -i 8188eu 
              $ cd /usr/local/etc
              $ sudo init.d/dbus start && sudo init.d/wicd start

              Assuming router uses WPA2...
              Click on the wicd icon, click on properties next to your router 
              name and pulldown and choose WPA 1/2 (PASSPHRASE) then 
              input your passphrase then click Ok. Next pulldown the button 
              top RH corner of GUI and select Preferences. Under Network 
              Interfaces input wlan0 (optional against wired input eth0) then 
              go to advanced TAB and click use dBm to measure signal 
              strength. Next click OK. Now click connect.

              To swap back to eth....click disconnect against your router
              then click connect against your wired network at top.

              COPYING file is for module license = GPL v2
              Real*txt is the license for the firmware file and names the author
              Example from $ dmesg | grep 8188  BEFORE SETUP

              AFTER SETUP dmesg should show an extra line

Change-log:   2018/05/17 first version used a restart daemon script
              2018/05/29 daemons were started by install script 
              2018/07/04 start daemons removed from install script 
              2018/07/08 renamed to 8188eu  
              2019/01/29  for 10x and modify build as no kernel headers 
Current:      2020/05/26  for 11x kernel and updated git source
