Help - How to change the Jetson Nano Micro USB port to host mode

Hello,

Jetson Nano J28 is fixed in the device role in the developer kit because its ID pin is floating.
I would like to plug the mouse into this usb port. I trying to modify the device tree and change the usb mode from otg to host, but still not work.
Is it possible to change this usb port to host mode? Please give me some advice. Thanks.

Best Regards,
Michael

I don’t think you can use that port in host mode (someone correct me if I’m wrong).

Hi linuxdev,

Thanks for your reply.

I forgot to say that I shorting the pin on J48 with a jumper.
Is it possible to change the micro usb to host mode under this condition that enable use of a DC power adapter?

Please give me some suggestion, thanks.

Best Regards,
Michael
