I have here 2 hard disks and 2 flash drives with USB 2.0. Three of them work 
on FreeBSD on an USB 3.0 port. One hard disk only works on a USB 3.0 port.

One hard drive with USB 3.0 does not work on USB 3.0 but only on 2.0.

Irony is that the PCBSD installer installed PCBSD on the USB 3.0 disk but it 
did not boot afterward.

Let me check this out.

Same as in my case.

USB is more a lottery than real computing for me.
