Mounting USB devices

[Trey Sizemore <trey@fastmail.fm>]

How can I tell how my USB devices are indentified in Linux?  I want to
be able to mount my Sandisk USB mass storage device to get pictures off
my camera's CF card.  I know through trial and error that my Zip 250 USB
drive is seen as /dev/sda1 so I created a mnt/sda1 to access it.  I have
several devices connected via USB including printer, mouse and scanner
in addition to the devices mentioned.  Here is the applicable portion of
dmesg:
