My ScanSnap has basically become useless in recent weeks and I can't figure out why. I have tried TWO different windows 10 machines, and neither will recognize the scanner. I have uninstalled and reinstalled on both computers. Updated software and drivers. Windows 10 just won't recognize the scanner, as I never see it in the device manager. I also press the scan button and it blinks 4 times and never runs the paper through. The ScanSnap manager icon is always greyed out too.
Weird - might be related to a windows update, as you suggested. Can not test it now since I do most of my work on my Mac these days. The Win10-machine is up to date regarding backups, but I only use it when I need to. Maybe I can come back on this when I use it next time, and will try to connect to the ix500 then.
Windows 10 never has recognised the scanner because Fujitsu use their own proprietary handshake connection and not the typical windows universal scan drivers. I've never had mine show up in the system devices list.
Basically, it seems like fujitsu has locked their ScanSnap products to only work with their software. Look at the 2nd answer here: -us/windows/forum/windows_7-hardware/fujitsu-ix500-neeed-wia-driver-to-use/704d680b-a866-4eed-9811-b166145a6bb0
after updating to 22h2, my fujitsu scanner 6110 no longer able to the scansnap software, as it is showed the device is not connected, while it is connected in the device manager, and i am able to use the build in windows scanner software.
The SANE team got it working by hacking up a backend for the ix500. It currently only provides color scans at the driver level (gray and B&W are done in software). Pull down the sane-backend project from the git repo, compile it, and install. There may be a few permission problems, but as root, I can run simple-scan and get everything I want out of it.
