Connot use plustek scanner also detected by sane-find-scanner

Hello. I recently received a recovery scanner plustek OpticSlim 1180. However I cannot scan with it (using xsane or simple scan).

The plustek website tells this should be supported by sane one way or the other.

I can however use sane-find-scanner and detect the scanner


  # 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.

  # Your USB scanner was (probably) detected. It may or may not be supported by

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

However scanimage -L is missing the scanner:

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).

I guess there’s some driver/module to install so that the scanner is recognized ? Can you help me ?

Thanks in advance,

A search for drivers gives this

but that only shows support for windows and mac.
An additional search for linux drivers gives
https://plustek.com/us/products/flatbed-scanners/opticslim-1180/spec.php
which shows

OS	Windows Vista / 7 / 8 / 10 / 11
macOS 10.10 / 10.11 / 10.12 / 10.13 / 10.14 / 10.15 / 11.x / 12.x
Linux compatibility is only available for system integrators. Please contact sales@plustek.com for more info.

There may be more info but I did not dig any deeper.

What are system integrators ? I guess I should contact that email…
