no scan when connecting with silvercrest- Negativ/Dia Scanne (SND 3600)

Its a known problem . I already know, the scanner is treated like a camera and the USB 2.0 entry is recogniced with code 0C45:6366 (Sonix).
Also it has a keyboard entry. There is a driver solving the problem when installing VUESCAN (scan result with water marks, but not the same functions as "Imagescan (V1.06.133d7.desktop)of Silvercrest product.
I am new here and wonder if Ubuntu 19.10 cannot help. (its not a function of Xsane)
