with modem on factory power supplyBeing a refurb , should not be an issue as you are just reading the flash .
Also try the above with power to pin2.
Also use a multimeter and get me the readings from pins 1,3,5,7,9
your wanting me to check the pins on the BCUSB itself or the modem. for some reason the more i read it the more i question what i checkedFor the readings , i want then direct from the pins on the BCUSB , no lead connected to the header.
I get 3.3v on all pins
When testing with pin2 , No power cord connected at all
