It’s reverse: you get a board that has a floppy interface on one side and a USB socket on the other. You plug in a USB drive and the board uses a file on the drive as the floppy disk, pretending to be a floppy Drive connected to the interface. It’s a little less convenient because you have to deal with disk images but it works without moving parts.
Look for usb floppy emulators, you can have the floppy images in a usb flash drive. No moving parts or need to find expensive floppies.
If this thing relies on floppy, I don’t imagine it would be USB compatible
