Hello List; I have 6 physical ports on my PC box. The boot time messages seem to say that one of those ports is 480Mbps High Speed USB v2.0. How do I determine which physical USB port is the 480Mbps High Speed port? The following are the boot time messages about USB ports uhci0: <Intel 82801EB (ICH5) USB controller USB-A> port 0xff80-0xff9f irq 16 at device 29.0 on pci0 usbus0 on uhci0 uhci1: <Intel 82801EB (ICH5) USB controller USB-B> port 0xff60-0xff7f irq 19 at device 29.1 on pci0 usbus1 on uhci1 uhci2: <Intel 82801EB (ICH5) USB controller USB-D> port 0xff20-0xff3f irq 16 at device 29.3 on pci0 usbus2 on uhci2 ehci0: <Intel 82801EB/R (ICH5) USB 2.0 controller> mem 0xffa80800-0xffa80bff irq 23 at device 29.7 on pci0 usbus3: EHCI version 1.0 usbus3 on ehci0 usbus0: 12Mbps Full Speed USB v1.0 usbus1: 12Mbps Full Speed USB v1.0 usbus2: 12Mbps Full Speed USB v1.0 usbus3: 480Mbps High Speed USB v2.0 ugen3.1: <Intel> at usbus3 uhub0: <Intel EHCI root HUB, class 9/0, rev 2.00/1.00, addr 1> on usbus3 ugen2.1: <Intel> at usbus2 uhub1: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus2 ugen1.1: <Intel> at usbus1 uhub2: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus1 ugen0.1: <Intel> at usbus0 uhub3: <Intel UHCI root HUB, class 9/0, rev 1.00/1.00, addr 1> on usbus0 Root mount waiting for: usbus3 usbus2 usbus1 usbus0 uhub2: 2 ports with 2 removable, self powered uhub3: 2 ports with 2 removable, self powered uhub1: 2 ports with 2 removable, self powered Root mount waiting for: usbus3 Root mount waiting for: usbus3 Root mount waiting for: usbus3 uhub0: 8 ports with 8 removable, self powered
