I tied USB_VBUS_EN0 (pin 87) to GND in my custom carrier board and when I connect a USB to Ethernet adaptor to the micro USB port it doesnt’ work. I am trying to elimintate the hardware design as an issue before I dive into into a software solution. The USB should be configured as HOST when I plug in the adaptor; we aren’t plugging anything else in there so we only need USB OTG to be configure the same way. I designed a carrier baord for the TOradex IMX6 and I tied vbus detect to ground and this did the job. I’m wondering if I may have made a mistake tying the vbus detect to gnd on the jetson nano because it’s an open-drain input.
I looked at the jetson nano product deisgn guide and noticed that they put a mosfet on that pin. I’ll be designing a new board shortly so I can make hardware mods if needed, but need to try fix this one to understand what to fix.
Any advice would be appretiated.
