The problem is that i don't know if it is an USB or something else!
No mention of it on the manual, nor on the board.

About a year agoi was measuring tensions in the output of a 15' monitor's
I forgot the tester on the OHM scale... it was making sparks and i didn't
luckily the multimeter wasn't damaged...
