Powered USB HUB [backfeed of RPi]
Hi! Ibought this HUB for my Raspberry Pi. It works, but I found strange thing: When I power off my Raspnerry Pi AC adapter, it (RPi) still gets power from HUB.
Is it normal and HUB should power my RPi? |

So.. you don't even need to connect the microUSB port of the RPi to this hub? Thats one less cable, would be nice.

yes,you do not need to connect micro USB to power up RPi as it can be powered from USB ports.but I do not recommend this
