No. The list of supported devices listed at www.sane-project.org does
not include the V100 but I hoped it would be supported as most Epson
scanners use the same backend.
There is actually a link to isane which does list a backend for the
V100. I downloaded a *.tar.gz file but the README notes that it will
only work if the sane frontend has also been built from a tar.gz file.
I hesitated to purge the Debian version of the frontend and so have not
been able to use the isane version.

As root scanimage -L responded device 'epson:libusb:004:002' is an Epson
flatbed scanner. I changed the permissions of /dev/bus/usb/004 and
/dev/bus/usb/004/002 to 777. Now as tom scanimage -L gives the same
response as root. scanimage >image.pnm still fails as described above.
