CZUR scanner not detected and not connectable

I have purchased this item

CZUR Shine Ultra Pro 24MP High resolution scanner for books 
USB Portable, Documents Scanner with OCR up to A3 format for 
home and office, Multilingual OCR viewer

https://www.amazon.it/CZUR-Dimensione-Riconoscimento-Multilingua-Compatibile/dp/B09NLMFQGN/ref=pd_sbs_d_sccl_3_7/258-9789812-9780105?pd_rd_w=7IhIg&content-id=amzn1.sym.a8225e34-6e10-438f-8794-fb84bb393cf4&pf_rd_p=a8225e34-6e10-438f-8794-fb84bb393cf4&pf_rd_r=PFVVAS9BZD4NYDEA0W33&pd_rd_wg=pC8Pr&pd_rd_r=393b1292-05ab-4a5f-8a69-2e65aa78c6cf&pd_rd_i=B09NLMFQGN&th=1

now, I had installed its CD under a VMWare Windows 11, and 
it worked all well (a bit slow, but a virtualized CPU / GPU 
intensive task is expectedly slower).


Now by mere chance, I discovered there is also a .deb 
package and dnld it from CZUR site and installed it in 
Debian Bookworm

The SW fails to automatically detect the HW, both launching 
the progmam with scanner disconnected and connectint it 
afterwards, or the reverse. Also it fails to manually 
connect with the main menu.

The strange thing is : Debian correctly reports sth attached
LSUSB¶
....
Bus 001 Device 012: ID 1e4f:2401  ET24A
....

and a very rapidly disappearing "video source" notification 
tooltip, of no usefulness, appears on screen on connection.

I just wrote a request on FB page of CZUR, but apart from 
that, what could be the problem ?

It is their own recent SW for the very corresponding HW, why 
should it fail ?

I am surprised ...
