RK3568 V1.4.0 SDK，USB OTG端子不能被电脑识别出adb设备，解决
修改后的/usr/bin/usbdevice：
#!/bin/sh
#
# Usage:
# usbdevice [start|update|stop]
#
# Hookable stages:
# usb_<pre|post>_<init|prepare|start|stop|restart>_hook
# <usb function>_<pre|post>_<prepare|start|stop>_hook
#
# Example hook:
# root@RK3588:/# more /etc/usbdevice.d/usb_init.sh
# #!/bin/sh
# usb_pre_init_hook()
# {
# echo "usb pre-init hook"
