Really? I was not aware that the number of wires matters.
I will check how I can reduce the number of wires on my breadboard.

Anyway, I was maybe lucky but I have just successfully done a circuit using a 
lot of useless wires here:

It is an USB connected breadboard that is controlled by a program on the 
computer [1, 2].
I can switch on or switch off the LED.

So it works here with this project but it does not work with the USBasp project?
