I didn't find anything obvious in tools/sane-find-scanner.c. My current
best bet is that this happens somewhere in sanei/sanei_scsi.c and that
this will very likely affect any backend that uses it (including epson,
epson2 and epkowa backends).
Maybe running with SANE_DEBUG_SANEI_SCSI set turns up something useful?
Hope this helps,
