All test cases were tested on bananapi-m2-ultra.

1. USB DEVICE(ping test)

Enable usb gadget rndis network, ping m2u on ubuntu host:

➜  ~ ping 192.168.200.2

2. USB HOST(OHCI)

Connect an usb serial port on OTG port, nex t is the kernel log:

[   27.824137] usb 2-1: new full-speed USB device number 2 using ohci-platform
[   28.865504] cdc_acm 2-1:1.0: ttyACM0: USB ACM device
[   29.565509] cdc_acm 2-1:1.2: ttyACM1: USB ACM device

3. USB HOST(EHCI)

Connect an usb storage on OTG port, next is the kernel log:

issues:
=======

The system power often turned off when I plugged an usb device into the OTG port.
It's not clear why.
