You may also want to run "tail /var/log/messages" after plugging in
the device. It will show you the port assigned, or show that Linux
does not know how to handle that specific device.

Here is an example of a properly detected device:
usb 2-1: new full speed USB device using uhci_hcd and address 6
usb 2-1: configuration #1 chosen from 1 choice
drivers/usb/serial/usb-serial.c: USB Serial support registered for
ark3116
ark3116 converter detected
usb 2-1: ark3116 converter now attached to ttyUSB0
usbcore: registered new interface driver ark3116

Here is an unknown device: (ETI2 eBook)
usb 2-1: new full speed USB device using uhci_hcd and address 7
usb 2-1: configuration #1 chosen from 1 choice

I trimmed the messages to fit - they all start with something like:
