Has anybody else managed to get USB networking to work on K3? Either via ;debugOn and ~usbNetwork or by simply by creating an empty file named ENABLE_USBNET in the root of the USB drive ? The reason I'm asking is that the start script is actually located in the test directory /test/bin/usbnetwork
If the /mnt/us/ENABLE_USBNET is empty, then it will be removed at the next reboot, so you get your USB drive back. If it contains the word "persist", then it will not be removed and/or if it contains "tethered", it will start in tethered mode.
Again, all this requires the script /test/bin/usbnetwork
Another interesting one is /mnt/us/ENABLE_VNC and it does not require the test files
