Thanks. The problem looks very similar to one reported in the past by Idwer. Unfortunately, Idwer also didn't have access to any other USB3 devices - that would have been a great test to see if the quirky behavior was due to the controller or due to the device.
Can you provide the output from "lspci", "lsusb", and "lsusb -t".

hi, Kevin, I am debugging the coreboot on AMD board.
I found if a device is populated on USB 3.0 port during system power up, the USB3.0 function fail after OS boot up. If a USB 2.0 device is plugged, the port is OK. Can you take a look at this?
What board is this, what USB3 controller is it, and what USB3 device did the problem occur with? Does the problem occur with multiple/all USB3 devices or just one?
