Graham this is an on going problem. See the openSuSE forum  at:
  http://forums.opensuse.org/applications/412870-virtualbox-usb-grey.html

My problem appears to be a conflict between VirtualBox and Iscan. Around May 
first on this thread there is talk of a solution #4 for this problem. It sort 
of works for me. It talks about diabling /etc/udev/rules.d/50-udev-
default.rules usb node section. This is after copying 50-udev-default.rules 
from /lib/udev/rules.d to the above etc directory. In my case, if the above is 
disabled all the usb devices work in VirtualBox on my XP guest. If it enabled 
then Iscan works but some VirtualBox usb devices are greyed out. I'm using 
iscan iscan-2.19.0-4.c2 on an Epson CX6600. The part about removing fstab 
entry for usbfs does not seem to make a difference at least on openSuSE 11.1.

People on this forum have said its not an iscan problem and on virtualbox list 
its not Vbox. I get the same message you get about not being able to send 
command to scanner. 

Not sure this is going to help you but it may provide something.
