[font=Verdana,sans-serif][size=1]What software would be best for use with a Play station style USB game controller???[/size][/font]
To confirm, you want to use it as follows:
PS2 controller -> Raspberry Pi -> 16 channel servo controller
Which servo controller do you have and what OS are you running on the Pi?
Note that most Raspberry Pis run Linux or Raspbian (or NOOBS), which means that if you want to compile code, Python is the best choice.
However, it will really be up to you to find appropriate sample code to receive the PS2 commands via Python, and program it accordingly.
You can actually get away with something a lot less powerful like the BotBoarduino with SSC-32U.
