Both wrong statements.
USB floppy drive are just as standard as USB disks. There is no need for a specific driver. It doesn’t matter if the manufacturer and distributor know about Linux or not.
The driver for internal floppy drives is unfinished and non-working, but the one for USB was working last time I tried it. Which I mentionned in this very topic a few posts earlier and this is why lelldorin has offered to test it again (I don’t have a working USB floppy drive anymore, so I can’t test it myself).
So it looks like the driver was broken somewhat recently and it is not working anymore. Is there a way to gather something useful from the KDL? Do you have at least an error message and a backtrace?
