I attached a picture of my working setup in another thread. This is the picture (extended with the http:)
On this picture you can see, the RPi was conneted to the powered usb hub with 2 cables:
On the botton-side connector of the hub there is black usb cable, this is, use to power the RPi. On the upper side of the RPi, from its USB connector run another blue cable to the hub,s control port. Actually I use the RPi-s second usb connector to connect the PCTV receiver, with a silver-like short cable. And, ofcoures, it has its own 12 Volt power connection, to drive the LNB. Maybe I can choose to connect it from one hub port too. I use the hub additional ports to connect a keyboard, and the wifi/AP adapter, if I try to use it. In the actual setup, preparing for a demo, I use a separated wired/wireless router to connect my latop with ethernet cable to this setup for more raliable and confortable use it. But through this separate wireless router/ap it can be access its web server on wifi too.
