Re: CanoScan Lide60 issues on Linux

This is pretty old sane
https://gitlab.com/sane-project/backends/-/releases

Simplescan is using sane as backend, but you may try a different 
frontend, including xsane:

But first, make sure what version of sane are you using, check if the latest, then check the already reported issues or you can run something like SANE_DEBUG_GENESYS="10" scanimage > out.pnm 2>genesys.log and analyze the log.
