This also happens if you're machine does not support USB 2.0

If you try:

  $ /sbin/lsmod | grep ehci
  ehci_hcd               31880  0
  usbcore               115716  4 usbhid,ehci_hcd,uhci_hcd


Do you see an entry for ehci_hdc?  If not, your machine probably
doesn't support USB 2.0.  The USRP requires USB 2.0
