I've got the same issue as this question.

My Raspberry Pi 3 will not power up when powered from a powered port on the same Amazon Basics Hub AND plugged into the 'USB In' on the Hub.

The linked answer states that the Hub is trying to backpower the Pi and that functionality is not supported.

I would prefer not to have to buy a different hub, so; Is there a way to stop a USB Hub backpowering?

Something like an USB A to B cable without the power component, or could I open up the Hub and remove a connection to stop it sending power?

The Hub will only ever be used to run my Pi so I don't mind making 'destructive' mods to it.

Thanks

You are misinformed as are some of the comments. You CANNOT backpower any Pi since the B+ (I reserve comment on the Zero) because the Foundation included proper protective circuitry. There is no published circuit for Pi after the B+, but the power circuit for later versions is assumed to be similar. Inspection of the B+ circuit clearly shows that backpowering is impossible.)

Neither can you power the Pi3 from a compliant hub because it will not supply sufficient current. (It was possible to run earlier Pi because their power requirements were more modest.)
