Check out Greaseweazle or Flu圎ngine or SuperCard Pro for examples. it won't show up as a 'drive' but instead you use custom utility programs to read and write raw images to the disks. However there are a number of projects that provide special hardware that is also USB but use their own apps to actually access the disks - i.e. These show up as drive letters in Windows and are convenient to use but not very powerful. The controllers on the USB floppy drives available these days tend to only support a narrow range of DOS formatting and not much else. Some options I see: Low level floppy controller

Happy to be shown wrong by other answers, but I suspect you're going to need some additional hardware. HFVExplorer may be convenient in that it (probably? iirc) supports Disk Copy images that you would otherwise have to strip the header from. But if it fails, you can use any raw disk writing tool you want once you have the images prepared. The program is very old and the source code is lost. I have heard of people who couldn't get HFVExplorer to write to physical floppies. HFVExplorer can also write the image to the floppy for you. You can either download raw disk images containing the software you desire or create them yourself using HFVExplorer. If you don't already have Apple File Exchange or System 7.5 with PC Exchange, you can write a Mac-formatted raw disk image containing them to a floppy using Windows and your USB floppy drive. System 7.5 introduced PC Exchange, which allows FAT floppies to be mounted in the Finder.

You need to use the Apple File Exchange application that comes on one of the supplemental system install disks. In System 7.1, you cannot read FAT-formatted disks by inserting them in the Finder. The SE/30 has a high density floppy drive that is compatible with USB floppy drives.
