How do I enable USB1_DP, USB1_DN, USB2_DP, USB2_DN as shown on page 22 of the OEM Product Design guide?
I’m using an Aerocore 2 for Jetson carrier board with a TX2. I have their official BSP installed, although the manufacturer’s support is fairly non-responsive.
I’m trying to get a Sierra HL7688 LTE module working, and their sparse documentation shows it connected to another USB bus on the TX2 (“USB2_2”). I’m guessing it’s the same D+/D- that is used for M.2 in other carrier boards.
In short, with the module plugged in it doesn’t show up at all in lsusb -t. That second bus isn’t even showing up at all.
