No one told you that this was how the device got mounted. These are the
udev rules that create the sd* devices.

Rod, we have two issues here and the first (can't mount) needs to be solved before the second (automount). The second depends on the first. If you can't mount the flash drive manually, you certainly can't mount it automatically.

So:

We've got the output from your dmesg and we know that mount -t vfat /dev/sdb1... fails. What we don't know is whether udev is creating /dev/sdb1 for you when you insert the flashcard. Please check that: ls -l /dev | grep sdb should provide the relevant output.

I am assuming that udev is not providing this device. Frankly this doesn't make sense to me as mine works just fine without any special rules. But, systems are different. Based on my assumption above, you need to write a special udev rule for this card. incidentally, this will give you the oppportunity to give it a persistent name as well, such as /dev/flash or whatever. Once this problem is solved, and it mounts manually, you can look at the variety of automatic mounting solutions.
check this for udev rules: http://www.reactivated.net/writing_udev_rules.html

Excuse me, but we are jumping the gun here. First, let's rule out
other problems.

I didn't see any email that indicates that you looked in /dev and
did, or did not, find a device special file for your device.

If you didn't find one, that's OK, because you can simply create
one.

After creating it, try mounting your device. If that works, then
we know that everything else is fine, it's just your udev configuration
that needs to be debugged.

Udev doesn't do automounting, it does automatic device special file
creation.

If you look in /dev and don't see your device special file, udev may
be the problem, but if you do look, and see it, then maybe something
else is wrong.

You need to post the contents of the /proc files I asked for.

When you dump what USB sees, you should see something like:

T: Bus=02 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 2 Spd=12 MxCh= 0
D: Ver= 2.00 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1
P: Vendor=03f0 ProdID=4002 Rev= 0.01
S: Manufacturer=HEWLETT-PACKARD
S: Product=HP PhotoSmart 935
S: SerialNumber=ZPP300000880
C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr= 10mA
I: If#= 0 Alt= 0 #EPs= 3 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=83(I) Atr=03(Int.) MxPS= 2 Ivl=255ms

The above indicates that there is a HP Photosmart 936 camera, in mass
storage mode, attached. Looking at this info I know that this is
a Bulk Only protocol device, that uses SCSI, so the SCSI sub-system
should be in play. I can check that by looking at what is in the
/proc/scsi directories.

Poke around in your USB and SCSI /proc directories, let us know what
you find.

Please correct me if i'm wrong but isn't the answer right there in the very
first posting.

Feb 5 13:16:31 localhost kernel: Attached scsi removable disk sdb at scsi6

It's saying the device is scsi6

so shouldn't it be

mount -t vfat /dev/scsi6 /media/flash


?
