Scanner hell - any ideas?

Aer spending most of the afternoon trying every [possible combination of
software - even using a windwos driver from a virtual - I have decided
that my scanjet2400C is borked hardware wise. Just wants to scream and
buzz instead of retracting its scnning head. Oddly it works on reboot,
but just for one scan..

so plugged in a dreadful old HP2100C and tried to get that to play nice.

No joy. Scanner not detected.

Softwarre is

Now the USB subsystem is detecting the scanner allright.

And there's an entry for in libsane udev rules which presumably puts it
all there.,

# Your USB scanner was (probably) detected. It may or may not be
supported by
# SANE. Try scanimage -L and read the backend's manpage.

...but not where it expected it to be...

but no sane software picks it up..
othello-mint log # scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Libsane ought to support this lot under the plustek USB backend, and
that all seems to exists.

Now I THOUGHT that the udev stuff would create another device like
/dev/usbscanner or somesuch but it aint.

Does anyone know enough how this OUGHT to work to see where its going wrong?

Try with VueScan. (http://www.hamrick.com) It's an excellent piece of
software, as opposed to xsane and libsane which are dreadful pieces of
s...omething.
The good news is that ScanJet 2100C is supported by VueScan:

The bad news is that VueScan is not free. I purchased the $80
"professional edition" license and have never looked back.

BTW, other than being a customer, I have no affiliation with the seller.

actually I fixed it. I had removed anything extraneous from
/etc/sane.d/dll.conf including an entry to use 'plustek' driver.. :-)

I remember doing that to get the previous scanner working
