I designed a custom PC board for a new product using the Jetson TX1. I connected the USB_SS0_RX and TX diff pairs and the USB1 DP and DN connections. The low speed USB2 port enumerates and works fine.
However the Super Speed USB 3 port does not work at all. I’ve carefully checked the connections and the differential pair impedances.
I have seen in some forums that it needs to be enabled and it is. Also if I plug my TX1 module into the Nvidia TX1 evalaution board the USB 3 port works fine.
Are there any other signals that have to be enabled in order to use the USB_SS0_TX and RX signals?
