Jaime,

please find attached the files.
In the conf. file there is a line near the top that says: firmware 
/home/hans/u176v046.bin
so place the bin in your /home/jaime directory
The bin is directly from the CD of the scanner

By the way, after a reboot the scanner didn't work anymore, but after 
some time and for some reason (maybe other usb port) it works again

Lots of luck.....

Hans

firmware /usr/share/sane/snapscan/your-firmwarefile.bin

# If not automatically found you may manually specify a device name.

# For USB scanners also specify bus=usb, e.g.
# /dev/usb/scanner0 bus=usb

# For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux.
# /dev/sg0
