CanoScan D660U flatbed scanner not working

[karsta62]

kubuntu 16.04 64bit scanimage -L device `plustek:libusb:001:006' is a Canon CanoScan D660U flatbed scanner

scanimage -A attached. Scanner is recognized, but I can't see any "Sensors". Pressing the scanner's button does not do anything. Some time ago (years) I got it working with scanbuttond, but not anymore with anything.

I would be fine if I got the button to start vuescan, simple scan or what ever scanning software gui. scanimage.txt

It seems that SANE detects something:

Buttons: --button 0[=(yes|no)] [no] [hardware] This option reflects the status of the scanner buttons. --button 1[=(yes|no)] [inactive] This option reflects the status of the scanner buttons. --button 2[=(yes|no)] [inactive] This option reflects the status of the scanner buttons. --button 3[=(yes|no)] [inactive] This option reflects the status of the scanner buttons. --button 4[=(yes|no)] [inactive] This option reflects the status of the scanner buttons.

Could you please check the following:

• if there are any visible changes in the output of scanimage -A if you run this command while holding one of the buttons pressed (try all buttons, maybe only one of them works)? The difference could be in the [inactive] or [no] parts of the output I pasted above.
• if something happens to the scanner or if there is some output if you run scanimage --button 0 yes for all buttons 0-4. Also try to escape the space like this: scanimage "--button 0" yes. It may output something or start whatever the scanner is supposed to do when you press this button or block until you press this button or just hang or break your scanner - I don't know.

It has two buttons only. The one that should start scanning software in windows I guess, and the other is for film scanning. I diff'ed the outputs of scanimage -A with and without pressing each of the buttons, but nothing changes. Outputs are equal.

It seems that scanimage (sane-backends) 1.0.25git; backend version 1.0.25 does not have any "button" option. scanimage --help output is the usual help with this additional info:

Then there is nothing I can do - you could ask sane-backend developers to add support for buttons in your scanner.

ok, thank you.
