This is really strange. Usually backends identify scanners by the
vendor and product ids and than either print the vendor/product
strings or they have their own list of product ids/names.

If this were the case here, this meant that the scanner was correctly
detected (maybe the backend prints always "SAMSUNG").

You could try to enabled debugging to find out whatÄs wrong. Check the
documentation of that backend (if any) for details.

I'm not sure if that's the reason.

No. Well, you could do that in the kernel or libusb with some tricks
but I don't think itÄs helpful.

Please subscribe. Otherwise I must manually approve every single mail
