On fedora 29 , sane-backends 1.0.27.

scanimage -L shows a number of scanners that are no longer connected,
and haven't been used in years.

In what file is this info stored ? Couldn't find any reference under
/etc/sane.d.

Is there a way to remove the old scanners from the command line ?

I found that /etc/sane.d/dll.conf had a list of all of the various interface/protocol/brands that sane scanned for on startup. If I commented out all but the ones I used (net and hp) that startup was much faster and it didn't search for devices that may have once been configured and are long gone.
