Here is my laptop (3 UHCI busses with 2 ports and one EHCI bus with 6 ports); /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=usb-uhci/2p, 12M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=usb-uhci/2p, 12M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=usb-uhci/2p, 12M > Also possible is that the wireing on the motherboard has a problem, > because the motherboard has 4 ports integrated. These ports work with > ohci. What can i do if this is the problem? I don't see how. You can load the ohci driver too for thost ports. > hub 4-0:1.0: Cannot enable port 4. Maybe the USB cable is bad?
