Comment on What’s the easiest way to pull ~30mA from a USB 3 port without getting a warning from Windows?

Do you get the same issue if you short the data lines? That’s usually the indication (to devices) that the port is for charging only; not sure how thats received in the reverse direction.

Looking at the PD spec I got the impression devices are supposed to pull the D+ pin up to a certain voltage, but I got lost partway through.
OP asked for the easiest way and deciphering the spec docs probably isn’t it.

For power delivery, ie requesting power outside the typical 5v 3a max; yes.
The charger sorting them together usually indicates to the device, it’s fixed at 5v 3a.
I think the device shorting them will indicate to the charger/port that you’re only requesting power @ 5v 3a max; but I haven’t died into the spec.
I’d give that a try and dig further if it doesn’t work.
