      Problem: The external SCSI-Scanner, known to be seen by antiX19-32 bit flawlessly, is invisible to the 64bit System running under antiX21 now, even when connected, line terminated correctly, powered on, and scsitools have been installed.

      	$ scanimage -L
	No scanners were identified. If you were expecting something different,
	check that the scanner is plugged in, turned on and detected by the
	sane-find-scanner tool (if appropriate). Please read the documentation
	which came with this software (README, FAQ, manpages).

      When using the command rescan-scsi-bus.sh the very device was found immediately by antiX 19 (32bit), and properly addressed:

      Summary so far: The Adaptec-SCSI-Card (pci) was obviously recognised, kernel modules were installed and loaded properly. Consequently everything should work, but the recgognition of the scanner by rescan-scsi-bus.sh fails now, running it in antiX21 64bit. Why so?

      After having checked and tested lots of additional command line options (see: man rescan-scsi-bus.sh) did the trick finally, after many try and error. It were the combined options -a -w –largelun which discovered the Scanner finally in antiX21-64bit:

      Test scans using easyscan worked fine after this, but I didn’t see any reason why the behaviour has changed from antiX 19-32bit to antic 21-64bit and the scanner is not found anymore with the default command settings. Strange thing. But this notes may help other users to solve similar scanner problems in antiX 21.

      Windows is like a submarine. Open a window and serious problems will start.
