it is not necessary to verify the result of the driver integration step above, if you want to be sure that the
driver is now associated with your modem. Attach the modem to the target board and run the following on
the command-line:
"dmesg|grep -i ttyUSB"

usb 2-1.3: generic converter now attached to ttyUSB0
usb 2-1.3: generic converter now attached to ttyUSB1
usb 2-1.3: generic converter now attached to ttyUSB2
