Hi again,

meanwhile I found some time to improvise a powered USB connector.

The plug is now powered by an external 5V 2.5A supply. USB signals D+, D- and Ground are connected straight through, power is supplied by external PSU and is routet over the blue jumper so I can measure current in case I want to know it. What I now have is:

USB Voltage 5.03V (while hashing)
USB-Serial converter 3.28V
PLL/Com: 0.998 V
ASIC: 0.83V

What I'd like to know is the voltage close to U5 (violet point) on the picture in below URL

I think this is the PLL Voltage as the ASIC has different Voltages for Clock and Operation.
Operations Voltage seems ok but I'm not sure about PLL Voltage. Maybe someone can measure his Ant
for PLL voltage. Due to specs Core is 0.75 - 1.1V, IO is 3.0 - 3.6V and PLL 0.9 - 1.1. So my values should be ok, main USB-Voltage is ok, current of 2.5A should suffice even at much higher clock rates but my ant is still a better block erupter
