Any board support OTG HNP?

[AristoChen]

I have an OrangePi PC and a BananaPi M1, and both of them are able to switch to USB host mode or device mode by editing dr_mode in corresponding .dtb file. But seems that both board are not able to support HNP protocol. 

 

From my understanding, OrangePi PC and BananaPi M1 only has perpherial-only OTG, please correct me if I am wrong.

 

Is there any board that can support HNP? I need something that can switch USB mode(from host mode to device mode or the other way around) without reboot the board

 

Any advice is appreciated

OrangePi PC can enable USB OTG by following the steps below.

$ sudo sh -c "echo 'g_serial' >> /etc/modules"

$ cat /etc/modules
