I tries lusb with and without the virtual machine running and got 
exactly the same result in both cases.
If the usb ports have somehow been assigned to the virtual machine how 
do I unassign them.
By the way the scanner is visible to both the ubuntu machine and the 
virtual machine.
Pth printer is a brother hl-w2130 and works perfectly with ubuntu and 
virtual machines on two other lenovo laptops.
Is it worth recreating Uubuntu  then adding in the virtual machine aqfer 
checking the prointer and scanners work in Ubuntu.  The cups program on 
the problem machine does not detect any printers including a networked 
samsung CLP-320N. All the other laptops can find and install this printer.
