I typically refer to /var/log/messages.  You'll see something like the
snippet at the end of the message (which in my case tells me the flash
drive is at /dev/sda).  I'm haven't delved into the way that USB drives
are named, but I seem to recall that udev is supposed to make the
assignments predictable and reproducible.

If you have multiple drives, check messages after each is added.

HTH,
