If the vendor and product numbers are already in the scaner module's
source code, the vendor= and product= options are not necessary. In
Linux 2.4.20, the 1660 is already known.

Or use libusb. With libusb the number of scanners is only limited by
USB specifications.

The kernel scanner driver is not part of SANE.

Yes. Basically, the number of scanners is unlimited. I've succeeded in
scanning from 3 USB and 3 SCSI scanners at the same time :-)

However, it depends on the backend if it is able to recognize more
than one scanner at the same time.

Usually, put the "usb vendor product" lines for your scanners in the
config files. Some backends detect all supported scanners automatically.
