avrdude done.  Thank you.

It works now :)
I have probably done a mistake on the wiring the last time.

As the this programmer contains a modified version of the opensource firmware 
on the fischl.de site, it means that I can't flash it with the original 
firmware if one day I need to upgrade the firmware.
Damned, they should not call this a usbasp programmer if it doesn't use exactly 
the original firmware.
If one day it doesn't work, I will buy a new one, I have no choice.

Since the usbasp firmware is distributed under the terms and conditions of the 
GNU GPL version 2, they should give the source code of the modified version of 
the firmware I have on my programmer.
Do you see this source code somewhere ?

Anyway at this moment, it works, so thank you a lot.
Best regards.
