I have a MS Sidewinder Precision 2 USB.
I works perfectly well uner linux. I cans test it in jscalibrator for example.

In Vendetta , it is well detected as an 6 axis and 8 buttons peripheral as I can see in error.log

The buttons work really well.
The axis don't... I don't know why... Any Idea ?

For your information:

Do the axes work in the joystick config menu?
If so, did you turn on joystick mode?

No they don't. And yes the joystick mode is "on"
