cat /sys/devices/platform/soc/usbc0/usb_device

#!/bin/sh

name=`basename $0`

usage() {

echo "$name Usage:"

echo ""

echo "$name [function]"

echo "function: mtp, support MTP function"

echo " adb, support adb function"

echo " uvc, support uvc function"

echo " uvc,uac1 support uvc and uac1 function"

echo "example:"

echo "$name uvc"

echo ""

}

enable_hid() {

#keyboard

mkdir -p /sys/kernel/config/usb_gadget/g1/functions/hid.usb0

echo 2 > /sys/kernel/config/usb_gadget/g1/functions/hid.usb0/protocol
