So, I updated my software to libftdi 0.8 and openocd r130,
without success.

I could borrow a multimeter today.
The fpc cable is good, the connector on the debug board seems good.
Testing the neo side gives stranges results.

The first test I made, was to verify contacts between the 45pins
 on the cable and the h-tp150[23458] dots on the neo pcb. It worked
 once.

Then I unplugged the cable, made various tests with both side
(un)plugged. There is continuity between the connectors (wire on the
white plastic), but the h-tp150* dots didn't beep again.

I didn't succeed anymore with the first test.      

Then, I try to use openocd, and notice that the neo screen flashes less
often. So the connector on the neo pcb seem's dead :(

I didn't have tools to make electronics and soldier wires to h-tp150*
dots, so I wonder if someone had already got success with scotch and
small copper wire ? wiring these dots to the 20 pins empty connector of
the debug board ?

P.S : 

What is the led7 on the debug board ? It blinks randomly when the
cable moves. And googling around, I didn't found if it is good that the
neo screen flashes and stay sometimes on until I launch openocd.
