Unfortunatly I am unable to provide the log at this time but kodi works fine until I plug in the usb
I plugged in the usb and let retropie create the file system and then i copy all the roms into their respective folders
I have wiped the sd card and reinstalled the os several times and I get the same results each time
Also once this happens retropie will no longer let me uninstall kodi either
hopefully this helps otherwise i will have to upload the log later

@An0nymouse go into RetroPie Set up. Choose Configuration / tools. Choose runcommand. Ensure Launch menu is enabled. Also ensure joystick control is enabled if you want to use it rather than a keyboard.
