Grab a Quick Start Guide, scan "USB Serial"-mode barcode, then "Save" barcode to make this setting permanent. Now your 3310g is in serail emulation mode, note new /dev/ttyACM0 or /dev/ttyUSB0 device. Read serial port with simple file operations from python:

f = open('/dev/ttyACM0')
print f.read(13)
