in order to have usb tethering, you need those two scripts:

pinephone-setup-usb-nework.sh:

Code:

#!/bin/sh

if [ ! -e /etc/NetworkManager/system-connections/USB.nmconnection ]; then
    # Create network connection
    nmcli connection add con-name USB \
                        ifname usb0 \
                        type ethernet \
                        ip4 10.66.0.1/8

    # Set priorities so it doesn't take precedence over WiFi/mobile connections
    nmcli connection modify USB ipv4.route-metric 1500
    nmcli connection modify USB ipv4.dns-priority 150

    # Share connection so it can be used for tethering
    nmcli connection modify USB ipv4.method shared
fi

and, pinephone-usb-gadget.sh:

Code:

#!/bin/sh

CONFIGFS=/sys/kernel/config/usb_gadget/g1
USB_VENDORID="0x1D6B"  # Linux Foundation
USB_PRODUCTID="0x0104" # Multifunction composite gadget

USB_SERIAL=`cat /etc/machine-id`

setup() {
    # Don't do anything if the USB gadget already exists
    #[ -d $CONFIGFS ] && exit 0

    # Required to make a composite gadget
    modprobe libcomposite

    # Create all required directories
    echo "Creating the USB gadget..."
    mkdir -p $CONFIGFS

    # Mount the MTP FunctionFS
    # echo "Mounting FunctionFS..."
    # mkdir -p /dev/ffs-mtp
    # mount -t functionfs mtp /dev/ffs-mtp
}

start() {
    echo "Enabling the USB gadget..."
    sleep 1
    UDC=`ls /sys/class/udc`
    echo "$UDC" > $CONFIGFS/UDC
}

reset() {
    echo "Removing the USB gadget..."

    # Remove USB gadget
    if [ -d $CONFIGFS ]; then
        echo "Removing gadget configuration..."
        # rm $CONFIGFS/configs/c.1/ffs.mtp
        rm $CONFIGFS/configs/c.1/ecm.usb0

        rmdir $CONFIGFS
    fi

    # Unmount FunctionFS and delete its mount point
    # if [ -d /dev/ffs-mtp ]; then
    #    echo "Unmounting FunctionFS..."
    #    umount /dev/ffs-mtp
    #    rmdir /dev/ffs-mtp
    #fi
}


case "$1" in

then run:

Code:
