Download and wireshark dongle.pcap. We get to know the device in package number 67: Teensy Keyboard/Mouse/Joystick. There is a working c implementation from http://www.pjrc.com/teensy/usb_keyboard.zip to figure out how the hardware is being used. Extract packages 102-2811 in human readable form and make it parsable.
