My Olympus digital camera model Stylus 800 (S-800) connected via a USB cable
would not automount in PCBSD 7.0.1.  It would not show up in Dolphin nor
would a small window pop up like it used to do in PCBSD 1.5.1.  This is the
same problem listed in the still-open Trac Item #156 (Olympus C-370Z not
detected or automounted)

#156: Olympus C-370Z not detected or automounted
---------------------+------------------------------------------------------
 Reporter:  udragon  |       Owner:
     Type:  defect   |      Status:  new
 Priority:  major    |   Milestone:  7.1
Component:  Misc     |     Version:  7.0.1
 Keywords:           |
---------------------+------------------------------------------------------
 The Olympus C-370Z camera is not detected or mounted on PC-BSD.
----------------------------------------------------------------------------

With my Olympus s-800 connected to the computer with a USB cable, I checked
dmesg to see if it was recognized.  It was because at the very end of dmesg
I found this:

%dmesg
<snip>
da2 at umass-sim0 bus 0 target 0 lun 0  <----- camera is recognized as da2
(because there are 2 scsi hard disks)
da2: <OLYMPUS uD800,S800 1.00> Removable Direct Access SCSI-2 device
da2: 1.000MB/s transfers
da2: 499MB (1023120 512 byte sectors: 64H 32S/T 499C)
GEOM_LABEL: Label for provider da2s1 is msdosfs/NO NAME.

mount_msdosfs: /dev/da2s1a: : No such file or directory  <---- does not
accept the "a" suffix  in /da2s1a
root at rtbank# mount -t msdosfs /dev/da2s1 /media
root at rtbank#                            <---- accepts and mounts the /da2s1
without the "a" suffix

<end dmesg>
Note:  Those are my comments following the "<------" pointers


Conclusion:

After using dmesg to discover what drive number has been assigned, you use
that information to construct the correct mount command.
The dmesg reports the scsi drive number assigned but does not report any
"slice" information.  The slice is most likely slice 1 (s1).
Ordinarily slices are subdivided into partitions a, b, etc.  In the case of
my Olympus S-800, it would not mount with a slice suffix.

Final command:  (Mounting as root)

#mount -t msdosfs /dev/da2s1 /media
