You cab try opening a couple of terminals and running

tail -f /var/log/messages           ( before you plug the usb device in)

 and

dmesg | tail                             (immediately after plugging it in)

This works, for instance, to see which /dev/sda* device is assigned to a
usb "pen" when plugged in. 

I haven't used a usb-serial device, but those commands might tell you
more than " lsusb " does.
