4.4 Default Mode Strings
When the USB port is connected to the Android USB port, the Android platform will determine which
application to load based on the strings read from the FT311D. These strings are configurable with a
Windows utility: FT311Cofiguration.exe available for download from the FTDI website at:
http://www.ftdichip.com/Support/SoftwareExamples/Android/FT311Configuration_V010100.zip
Default values for the strings are set in the device as per Table 4.2
