I got my floppy drive working in vista. but I had to get the drivers for the
device from the OEM. my 1.44MB floppy drive if from 1995. what type of
floppy drive are you running and what year is it from.
Vista only nativly supports LS-120, ZIP Disk, and JAZZ Drive type floppy
drives. however it will support low capacity floppy drives at times when
they are USB based, but just the newer ones.
For the floppy not showing up at all. in the device manager. do any "unknown
devices" show up in the list of devices.
