My scanner Mustek “ScanExpress 1200 CU Plus” is not operationel, xsane nor skanlite find it and here where i am:
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
# No USB scanners found. If you expected something different, make sure that
# you have loaded a kernel driver for your USB host controller and have setup
# the USB system correctly. See man sane-usb for details.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
But when i type lsusb the scanner is correctly detected on 5e line:

The Sane page tells that model is supported:
I think that, back in the days, I had a similar or even the very same one.
What was missing then - as it is today - is the firmware for this device.
I (back then successfully) searched and looked for that firmware and indeed found it.
Placed it where it belongs - and the device was functional.
So: maybe search for your device name and linux and firmware, see what you find and get the firmware … maybe even extract it from the original windows driver disc …
I’m pretty sure that that is what is missing here - and because it is so old and also probably proprietary - it’s not included in the default downloads/packages.
This will have to be done by hand, most likely.
There will be no ready made package …
That was the solution, the lone thing to do was finally to simply connect the scanner directly in the USB ports of the PC and not via a hub
Strange because my printer Canon works perfectly via this hub and this scanner has always been plugged in this hub, so why now do i have to connect directly on the PC i don’t have any faintest idea it’s a mistery, but at least it works !
Greatfull thanks to all the helpers and omano for the solution
