Sorry I didn't keep the thread, but, in case it is helpful, here is 
the line in my /etc/fstab for my USB stick plug-ins.   (There are some
other USB devices that use up da0 and da1)

/dev/da2s1              /stick          msdosfs rw,noauto       0       0

  I just plug one in, 
  su to root,
  type 'mount /stick' 

and then can read it just fine - even from non-root.
I do this frequently to suck .jpg files off the cards from 
my digital camera.  (I have an adapter to make them USB plug-in-able).

I can write as root, but I haven't messed around figuring out if
I can manage to write as non-root.

As you see, it is msdosfs or in other words, FAT32.
I don't know anything about the exFAT mentioned below.
