I ran into the same problem on Jessie, and after that into your mail on the 
list. Have you ever found a solution? 

For Jessie I did find a solution: use SCSI instead of USB. With modern 
computers it may not be a solution, because they mostly come without parallel 
SCSI interface, but that is a problem that can be solved via a second hand 
computer. 

I have not yet mailed VueScan about USB support, that may be another option 
(the usblib reference from hamrick.com to the Sane-help did not help me). 

In short: the VueScan can run the FS4000us on Linux via SCSI. Do not forget to 
set the switch at the bottom of the scanner from USB to SCSI. 

Best regards,

Boudewijn

PS: if my mail does arrive at your place but not at the debian-user-list, 
would you mind forwarding it for future reference?

Hi Boudewijn,

thanks for your answer. Unfortunately no, I didn't manage solve my problem. The
only solution I found from VueScan or other sources was to get (or write) a
custom driver. And indeed my PC does not have an SCSI interface. But I've found
that there are PCI extension cards for plugging SCSI devices. This could be the
solution, maybe I will try to explore that.

Thanks again and best regards,
Jean-François
