How to Enable USB Host mode on Night/Race

Product: [Jumping Race/Jumping Night]


The jumping Night/Race have USB port that is capable to Host/Device mode.
The detection is made by monitoring VBUS signal on the usb port. This implie that in Host mode, the port isn’t powered by the Jumping.
But if I power my usb device with an external power supply, the jumping dosn’t see it… like if Host mode was only for internal purpose (eMMC).

The question is : Is a way to bring the usb port in Host mode for externel USB device ?

Thanks a lot


P.S : In my case, by USB Device, I mean serial to usb adapter (loaded by insmod cdc-acm)
