  Craig,

  Followed Bernard's recommendation  'modprobe usb-ohci' then did 

  # lsmod | grep usb
    usb-ohci			18888
    usbcore			62604

  # mount | grep usbdevfs
    none on /proc/bus/usb type usbdevfs (rw)

  # egrep '^S:' /proc/bus/usb/devices
    S:  Product=USB OHCI Root Hub
    S:  SerialNumber=e0945000
    S:  Product=USB OHCI Root Hub
    S:  SerialNumber=e0943000

   
  The above looks better.
  As I am using Debian Sarge + a couple of bits from unstable 'apt-get install hotplug' 
  should do it, anyway thats the theory

  Thanks  Craig & Bernard, will let you both know how it progresses.

  Laurie
  PS  aaah a step closer.
