I'm going to answer myself here. I managed to solve my issue, it was in
fact a simple permission problem.

I changed my /etc/devfs.rules files by replacing 'usb' with 'saned':

	[system=5]
	add path 'ugen1.3' mode 0660 group saned
	add path 'usb/1.3.*' mode 0660 group saned

As Zsolt said, I removed the inetd service and simply let SANED share
the scanner over the network by itself and it worked.

Thanks for the help.
