Well, you could start by doing an internet search for USB PINOUT. That should tel you exactly what you need.

FYI, a 6p dpdt is not how it's said...

In the industry, we say 6PDT to mean six poles, two throws.

What you actually said (although I know better) could be interpreted to mean a 12 pole, double throw switch.
