Hello,

I'm having trouble with my TEAC (FD-05PUB) USB Floppy in 5.3-STABLE i386
on a Dell Inspiron 5100.

My problem appears to be that which is described in the following post(s):
   http://news.gw.com/freebsd.ia64/348
   http://news.gw.com/freebsd.ia64/347

I was wondering if a fix had ever been developed.  I have cvsup'd
RELENG_5 on Dec 19 2004, and the problem still persists.

To summarize.. I see things like this in dmesg
umass0: TEAC TEAC FD-05PUB, rev 2.00/0.00, addr 2
da0 at umass-sim0 bus 0 target 0 lun 0
da0: <TEAC FD-05PUB 3000> Removable Direct Access SCSI-0 device
da0: 1.000MB/s transfers
da0: 1MB (2880 512 byte sectors: 64H 32S/T 1C)
umass0: Unsupported UFI command 0x35
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x6, scsi
status == 0x0
umass0: Unsupported UFI command 0x35

status == 0x0
umass0: Unsupported UFI command 0x35
(da0:umass-sim0:0:0:0): Synchronize cache failed, status == 0x6, scsi
status == 0x0

... and ...

Opened disk da0 -> 6

Can mount the disk, ls the contents, but otherwise its useless.  Page
fault when umounting and/or if I remove device before umounting.

I have a kernel configuration including
    usb, da, ohci, uhci
as per a post I found (was there by default).

It was working in 5.2.1-RELEASE... maybe in 5.3-BETA7 (I think).  But
appears broken now.  It behaves this way with ACPI enabled and disabled.

I've googled, read the manual, searched the PRs, read UPDATING, etc,
etc... can't find the fix.  If I've missed it could someone please point
me in the right direction.
