I have a scanner (Fujitsu ix500) connected via USB with a Fedora 29 machine. I can use the scanner just fine using GNOME's simple-scan.
Also it seems the scanner is well supported via sane:
$ scanimage -L device `fujitsu:ScanSnap iX500:1244428' is a FUJITSU ScanSnap iX500 scanner
Now I want to run some (proprietary) Windows application which came bundled with the scanner. The application seems to work just fine using Wine Staging 4.0-rc4 (Fedora default). I have the "wine-twain" package installed.
However the Windows application only lists a "gphoto camera" but not the scanner. Is there anything special to make sane scanners available for Wine applications?
