Just to add to what Torfinn mentioned elsewhere in this thread: -
I use a CZUR ET16 Plus to scan things like pamphlets and Xmas cards
etc. I have to use it on a Windows machine because there are no Linux
drivers for it. Don't think of them as simply web cams. As Torfinn
hinted at, the real advantage of the proprietary software is that it can
automatically crop and rotate the image and even scan two facing pages
at once to produce both pages as separate images. The CZUR scanner even
fires off a laser just before scanning so it can estimate the curvature
of the paper. Then there is also the addition of a foot switch to begin
scanning if you have both hands full.
With scanners I have learned that one type doesn't suit all scanning
jobs. I also use a brother ADS-4700W sheet feeding scanner which can
automatically scan both sides of a sheaf of sheets and send the PDF to a
waiting server with the push of a button!
It's all a far cry from when I worked for Crosfield Electronics 40 years
ago. Those drum scanners were used in the printing industry and filled
a room!

Just curious, did the old sane backend do something more than, say,
"ffmpeg -i /dev/video0 scan.xxx"?
Anyway, I guess I have to take my chances and hope the el-cheapo book
scanners are standards compliant and don't use some proprietary protocol.
