I too have found USB3 to be less than reliable. I don't think I could do it; xhci_pci and xhci_hcd are compiled into the kernel (not as module). I know that if I restart the box the USB-3 will start working. The box has an uptime 130 days and is my main server. -- Thelma

Can you rmmod xhci_pci and xhci_hcd then modprobe xhci_pci? If that helps, it's a software issue, otherwise it may be a hardware fault that needs a reset.

I have an usb extension cord pluged-in to the back of the computer "blue usb port" (I think the color blue designates USB-3), there are two of them. My usb stick was working OK on one, but it stopped. I pluged the USB extension cord to the other port; so it was working for a while. Now the second one stop working as well.
