LOL it gets stranger! No I did not have the probes reversed. Usb was okay as I had a wireless dongle working fine. However,,,,, I had tested this and the multimeter a fair portion of the morning., multimeter was okay read voltage correctly on things like batteries but the pro with different gnd/vcc combos always came up reversed. |
Now I'm getting correct readings. The only thing that changed was that I had removed the usb supply from the board and reconnected to test once more after reading your post... go figure?
......and I just ordered another pro online from a seller here in Oz. Probably won't be able to cancel now.... oh well... sigh!
