Just had a look at the circuit of the V1 board:

I have 3v3 on PG6 (USB PWR)
I have 3v3 on the LED's

Going by the V1 circuit:

A: I don't have USB VBUS from the USB switch (U12 in the V1) (U8 in the V2)

B: There is 5v into switch U8.

Without a V2 circuit I don't really know what drives the Enable line to switch U8.

I'm sure this is just a link issue as I have TWO V2 boards and both are the same.

It's all too hard.
