Hi,we are encountering a USB 3.0 regression after upgrading our Jetson platform from release R36.4.3 to R36.5.0.
On the previous release (R36.4.3), both USB 2.0 and USB 3.0 devices operated without any issues. After the upgrade, however, USB 2.0 still works as intended, but the USB 3.0 Hub is no longer detected, and USB 3.0 devices are never enumerated or assigned to the USB 3.x root hub.
lsusb output with a USB-C SanDisk flash drive (verified on dev-kit to appear as USB3.X) in the port:

The simplified diagram of the port connection is as follows:
