This happens when either your machine doesn't have a USB2 controller
(EHCI) or when the EHCI module isn't loaded.

On one of my SuSE 10.1 machines I get this:

address@hidden mail]$ lsmod | grep -E '(usb|ehci)'
usbhid                 44640  0
ehci_hcd               31880  0
usbcore               115716  4 usbhid,ehci_hcd,uhci_hcd
