I am trying to make my Pi 3 work with one of the external HDDs I have at home.
A few of them have both USB input and power supply input, others have only USB input, but bigger capacity, which I prefer. To use such a HDD I decided to buy power-supplied USB hub. The main question I have is the following:
Can I plug Pi's micro-USB power input into one of the hub inputs, while still using another hub input to power the HDDs and connect them to the Pi via the hub's output?
This will result in the only socket-connected device being the hub. It seems strange to me that the Pi will be getting data from hub's USB, while being connected to the same hub itself.
