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".
