Does your PC have Intel CPU and USB 3.0 ports?
Do you see following messages in dmesg when boot kernel with "-x"?

xhci0: USB3PRM / USB3.0 configurable ports: 0x0000000f
xhci0: USB3_PSSEN / Enabled USB3.0 ports under xHCI: 0x0000000f
xhci0: XUSB2PRM / USB2.0 ports can switch from EHCI to xHCI:0x0000000f
xhci0: XUSB2PR / USB2.0 ports under xHCI: 0x0000000f

If yes, adding "userconf disable xhci*" to boot.cfg may avoid the problem.

The xhci driver tries to route all USB ports (even 2.0) to xhci
as possible if it's Intel PCH, but current xhci driver still has
problems about recognizing devices.
