Another reply already suggested that the USB controller doesn't give the
And fdformat's man page only mentions /dev/fd* devices too.
I probably should disable or hide that option in case of other devices than
fd0/1 or try to find a different tool to use.
Currently, there will be a (hopefully) comprehensible error dialog if you
enter a custom device though.
I have to admit I don't know if a low-level format would be possible or
necessary in such a case.
For "normal" floppy drives this is important though.

On my openSUSE system, mkdosfs and mkfs.vfat are just symlinks to mkfs.fat.
So I would expect all of them to work, or not.
But the difference is probably the '-I' option, adding this would of course be
For the record, this is what the man page says:
-I It is typical for fixed disk devices to be partitioned so, by
default, you are not permitted to create a filesystem across the
entire device. mkfs.fat will complain and tell you that it
refuses to work. This is different when using MO disks. One
doesn't always need partitions on MO disks. The filesystem can go
directly to the whole disk. Under other OSes this is known as the
'superfloppy' format. This switch will force mkfs.fat to work
Shouldn't do any harm to use it even for "normal" floppy drives, I think.

Yes, that's the plan now.
