Which USB post is 2.0?

[Dotan Cohen]

My machine has 6 USB ports, 2 in the front and 4 in the back. While
playing with lshw I found this:
        *-usb:2
             description: USB Controller
             product: USB 2.0 Controller
             vendor: Silicon Integrated Systems [SiS]
             physical id: 3.3
             bus info: pci at 00:03.3
             version: 00
             width: 32 bits
             clock: 33MHz
             capabilities: ehci bus_master cap_list
             configuration: driver=ehci_hcd
             resources: iomemory:cffdf000-cffdffff irq:10
           *-usbhost
                product: EHCI Host Controller
                vendor: Linux 2.6.17-10-generic ehci_hcd
                physical id: 1
                bus info: usb at 2
                logical name: usb2
                version: 2.06
                capabilities: usb-2.00
                configuration: driver=hub maxpower=0mA slots=6 speed=480.0MB/s

So, one of the pairs is USB 2.0 capable. How can I figure out which
one it is? I have a USB 2.0 disk on key, but it seems to be the same
speed at all the ports. I know that Windows XP tells you that you've
plugged a USB 2.0 device into a USB 1.0 interface, how can I get the
same info out of [K]Ubuntu?

Thanks in advance.
