Yes, both scanners are listed, but there is no "Set as default" option that I can find.

After a lot of experimenting with installing/removing drivers and software, I have come to some conclusions. Probably wrong conclusions, but I don't claim to be smart.

I don't think it is a driver conflict problem. The scanners show themselves to be on separate USB ports, and both scanners pass the Windows diagnostic test. See the screenshot.

Operationally, the problem seems to be that if the EpsonScan UI software is installed, it takes over any and all scanning operations, that is, it won't let me use the Fujitsu scanner even though I start out using the Fujitsu's software. As soon as I tell the Fujitsu software to scan, it brings up the EpsonScan software and the job goes to the Epson.

If I then go to Devices and Printers and Uninstall the EpsonScan software, the Fujitsu works properly.

I went so far as to rename the escndv.exe program, and the damn thing still ran. The only way I can find to stop it is to do a full Epson uninstall.

Knowing that, I suppose I could put shortcuts to the Epson Uninstall program and the Epson Install program in my Scanners directory and on the rare times I need the Epson flatbed scanner just install it and uninstall it when I'm done, but that is far from an elegant solution. Pretty ugly, actually, it would almost be easier to just leave it on the iMac. [shudder!]

I dunno what to do from here.
