Thanks for the logs. In the first log, all device I/O looks fine. In
the second log, the backend indicates that it did not get a reply to the
very first command it sends to the scanner. There is no information on
why. Could you provide a log with the low-level USB debug messages?
SANE_DEBUG_SANEI_USB=255 scanimage -L
should do the trick.

Don't think so.
Hope this helps,
