Hi, I have here a several storage devices which all work in different FreeBSD machines on USB 2. Some of them also work on an USB 3 port but most fail. Even one USB 3 device works on USB 2 but not on USB 3. As at least two USB 2 devices work both on USB 2 and USB 3, I expect the USB 3 port of the computer to work properly. I did some trial and error testing but could not get a clear picture. What would be a good strategy to find out the difference which causes the failure? Erich
