I am trying to set up a Nikon Coolscan IV
under Ubuntu 10.04, kernel: 2.6.32-32-generic

     scanner (vendor=0x04b0 [Nikon], product=0x4000 [LS-40 ED]) at 

     scanimage --version:
     scanimage (sane-backends) 1.0.20; backend version 1.0.20

     scanimage -L:
     device `coolscan3:usb:libusb:005:002' is a Nikon LS-40 ED film scanner

But when I do a test via
     scanimage -T
I get a:
     scanimage: open of device coolscan3:usb:libusb:005:002 failed: 
Invalid argument

It didn'tt matter what other options I tried setting with scanimage.

I am assuming this is an "obvious" error to somebody, but I could not 
find anything
to help me resolve this. Any pointers as to what may be going on or 
where to look next?

Thank You,
