I didn't noticed the IESO is defined on USB samples. I had a through hole metalization problem on the crystal (I have now the ability of manufacturing the PCB completely in my lab, but the electrochemistry issues with 0.4 and 0.6mm holes are quite nasty...it's a big challenge) thx, Vasile > > Regards, Rob. > > -- > R.
