I don't know of any articles, but here is what I do:

$ uname -r
$ ls /dev | grep ^da

(note that there is nothing found) ...and then plug in the thumb drive 
and do it again:

$ ls /dev | grep ^da

...and now I can mount it. Since this drive is a FAT32 filesystem, I use 
mount_msdosfs. Having an entry in /etc/fstab is a convenience but not 
strictly necessary.

After pluggin in my thumb drive, my dmesg shows

da0: <SanDisk Cruzer 1.02> Removable Direct Access SCSI-2 device
da0: 40.000MB/s transfers
da0: 7629MB (15625216 512 byte sectors: 255H 63S/T 972C)

Note that while dmesg only shows da0, my `ls /dev` also shows da0s1. You 
may need to use /dev/da1s1 or similar (depending on what you see from 
`ls /dev`) in your mount command. Try a few permutations.

HTH, and maika'i pomaika'i.
