Trouble with TEAC usb floppy (FD-05PUB)

[Eric Schuele]

Hello,

I am having difficulty with my TEAC usb floppy drive (FD-05PUB).  I'm 
not really sure what's wrong.  Plugging it in.. it appears to get 
detected.  But it is unusable.  I always get a 'device busy' after 
mounting it.

Attached is a dmesg obtained after booting with the drive plugged in. 
Also of note... the "* was not properly dismounted" is due to the fact 
that FreeBSD gave up on the buffers when shutting down... because of the 
floppy.  If I'm luck it gives up.  Sometimes I get a kernel trap.

This has been an ongoing problem since 5.2 (Presently running 5.4-STABLE 
as of a few days ago).

Is anyone else seeing this problem?  Should I file a PR?  Its been going 
on for quite sometime.

Any help is appreciated.  If anymore information is needed please let me 
know.

Regards,
Eric
