How to install when you do not speak technical English?

When connecting the phone. USB on the computer Window seven, the HP and the microphone works well.
For the rest, no explanation in French, an easily readable and incomprehensible technical English manual.
On the CD, no explanation for installation in the language of the French vendor is therefore no function on the keyboard.

It's really not good and not serious.
The device seems well but you have preut also be be alert to the user because it is not every computer technician.
Too bad, Verily shame because in addition there is nothing on the internet .....
