   This is good.

   Check the last few (dozen) lines of dmesg.  For example, from
plugging in my iRiver portable drive:
hub.c: new USB device 00:1f.2-1, assigned address 8
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 8
SCSI device sda: 39063024 512-byte hdwr sectors (20000 MB)
 sda: sda1

   The messages might be slightly different depending on kernel
version and modules already loaded.  the important part is the
"SCSI device sda" line.  Then I can do:
# /sbin/fdisk -l /dev/sda
...
   Device Boot    Start       End    Blocks   Id  System
/dev/sda1             1      2431  19526976    c  Win95 FAT32 (LBA)

   That tells me to mount /dev/sda1.  Remember that USB drives get the
first available SCSI device, which WILL change as devices are swapped
around.  There's a system called devlabel to handle this, but I'm too
lazy to explain that right now.
