USB floppy drive work with Built-in Driver of Mac OS X. Do not install driver from driver CD-ROM.If you want force to take USB Floppy on current version: Apple will fix this problem on future update. But current version of Apple's Mac OS X driver has problem with mount and un-mount operation. Just now, I received a mail from Y-E Data: Apple will support USB FDD on Mac OS X with built-in driver.
There are two other variants one made for the early iMacs, and one for Windows. They call it 'USB Floppy Disk Drive FlashBuster-U' and 'USB FDD SNAP-ON Color Cover Model'. Even more so that LaCie offered no support on this drive whatsoever! The drive is not manufactured by LaCie at all, it's made by Y-E Data, a company in Japan. I bought a LaCie USB Floppy along with my G4/450 DP, and of course the fact that OS X dosn't support it is rather frustrating.
