Saves on the requirement for mains plugs too! Just make sure you get a PSU for the Hub thatis beefy enough - I'm using the £6 ebay pluscom hub with 3A PSU, works a treathackery21 wrote:So I can use a powered hub as a hub for the pi AND also power the pi with it?
No, this connection is fused on the PI with a 140mA fuse, so you also need to use the micro USB power cable and plug it into the hub.domdoran wrote:I noticed that when connecting the USB data cable from the powered hub that the pi powers on without even connecting the micro USB power input to the pi. Is this how you guys are running, or are you also connecting the micro USB from the hub to the power input of the Pi?

I second that, especially the bit about the 3.5A PSU.
I am also using short cables (30cm), which makes it all neater: But also minimises voltage loss in the USB to Pi power cable:
A 30cm elbow micro-USB to USB-A for power - makes it easier to route the power cable to the rear.
A 30cm USB-A to USB-B for data.
An elbow HDMI adaptor - makes it easier to route the HDMI cable to the rear.
The Raspberry Pi hangs on the wall at the left of my desk, with the Pluscomm USB hub below it, on its stand.
The power and USB from the hub to the Raspberry Pi, and the power from the mains to the hub are on the right, as in the photo. An old 80GB USB powered HDD is underneath, connected to the 2nd USB port on the right end of the hub.
The sockets on the 'front' (left) of the hub are free for peripherals: at present a USB stick and a small wireless dongle for the keyboard/mouse.
As soon as it arrives, I'm going to replace the HDD with a 16GB USB stick and hopefully have the rootfs and swap on that, just leaving /boot on the SD card.
