Done setting up as USB gadget
You must reboot for changes to take effect

If you chose to use dnsmasq, then
you can reach the device on 10.55.0.1 when connected by USB.
If not then your host must assign an IP address to the usb0 interface.


If you want to disable the usb0/gadget interface then
please run 'sudo systemctl disable usb-gadget'
and reboot.
