Problem with NEC USB floppy UF0002

Hello,

Some troubles trying to use an external NEC USB floppy, model UF0002.

After connect it, driver seems to recognize it:

Feb 25 12:46:43 kernel: usb 2-1: new full speed USB device using
ohci_hcd and address 6

0, id 0, lun 0, type 0
Feb 25 12:46:52 kernel: usb-storage: device scan complete

but the error "unknown partition table" appears.

All my tries to mount it have failed.

Finally, I can read the floppy content in a two steps operation: dump
all floppy content to a file, and mount the file:

dd if=/dev/sda of=/tmp/foo
mount -o loop /tmp/foo /mnt/floppy

any sugestion about what is hapenning?

Thanks a lot.

PS: I've tried to post in the USB users list, but for a unknown reason
the email is rejected with answer "Message rejected by filter rule
match".
