Hi,
We use u-blox GPS module NEO-M8N connect to usb port on OrinNX SOM and Xavier NX CA board (P3509), and that can found new UART port /dev/ttyACM0. When we first time to open that port /dev/ttyACM0, that can get gps data, but close and open again, no data come-in. When change SOM to Xavier NX, this behavior is work, any open/close no problem. Advance we try to use OTG port to connect GPS module by use OrinNX, and open/close can work too, but when we connect a usb hub to OTG port and connect GPS module, open/close not work again. That conclusion is when GPS module connect to hub to usb root on OrinNX seems not work. Any idea to solve that ?
Regards,
Kevin
