Hello, I have noticed that my BBAI Rev A1, when connected to a PC, will enumerate as a high-speed USB device with the USB-C connector in one orientation, and a Super-Speed device with the connector oriented in the other direction (simply flipped upside down). I have reproduced this across several software revisions including the production emmc image: http://debian.beagleboard.org/images/am57xx-eMMC-flasher-debian-9.9-lxqt-armhf-2019-08-03-4gb.img.xz
I checked the https://github.com/beagleboard/beaglebone-ai/wiki/System-Reference-Manual#board-changes page and did not see any changes related to USB in any of the newer revisions. I was wondering if there are others who also have experienced this issue, or if it could be isolated to my specific board. I have reproduced the issue with several different USB-C cables including a USB A->USB-C and USB-C -> USB-C cable.
