The above pretty much translates to "a vintage PC must be used". Many of the old utilities like the Sydex drivers access the floppy controller at a low level, so that's why USB drives won't work. A list of tested floppy controllers can be found at Daves Old Computers. Here's the list and an FDC test.

I use a 450 MHz PII and an Adaptec AHA-1542B for the floppy controller. I can disable the L2 cache and get it to behave like a much slower machine making it compatible with tools like LIFUTIL.
