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?
Something like

  SANE_DEBUG_SANEI_USB=255 scanimage -L

should do the trick.

Don't think so.

Hope this helps,
