Have wheezy downloaded to my raspberry pi. I have a 7 ports hub with no brand name (stand up). There are 7 usb ports and another that looks like a printer usb that is a regular usb on the other end. Is this for a usb power connection? and would it be 700 ma. The pi needs 700 ma to operate with no problems. I hope to have this up and running this week as well as the "over the air" Hdtv antenna in less than a week.

For some reason my phone is not posting the picture, but my computer did. That's why the blank posts. A problem for another day.

My monitor is a 24" hdtv. As you can see in the picture, I have a 3 to 1 hdmi switch. The tv has only one hdmi input. I may try to get the over the airwave hdtv antenna to use the other port and have computer, antenna, and pi choices for this stage of experimenting.

The 7 Port USB Hub must have a power supply and then you run the cable from the USB Hub to the USB Micro Port on the PI.

I bought an 800 ma power supply to power the pi. More this weekend.

I have overcome some problems and am writing this on my raspberry pi system. I read that using a usb hub would overwhelm the pi and keep it from getting on the internet. Well, I used the two usb ports, on the pi, for the mouse and the keyboard and I still could not get online. In my case I have a bad ethernet cable or a faulty switch. it is getting too late for me to go on tonight. Will get back later to see if it's the ethernet cable, switch, usb hub, or all.

Ordered some cat6 cables and a 16 port gigabit switch today. I will be able to experiment with an Android 4, with the new switch and my 3 into 1 HDMI switcher. Tonight I'll try the known good cable and port with the powered usb hub. I will also go to the Pi blog/forum to report and learn more.

I think I'll get one since they are available now with the accessory parts needed.

Hard to find.

May be get a 2 or 3 mini hdmi port input switch and NOT use one of the input ports.

This would be the same as off to the output port.

I bought an approved Plugable usb powered hub for the Pi and am going to try the other (posted by raphonix) hub on the Android 4.0 mini. I am wondering if I can have wheezy on one sd card and plug and play another sd card with another version of Linux, interchanging them at whim, on the Pi? I will send a picture tomorrow. I am told to do the income taxes first though.

I am also going to place a power strip on the desk to use as an on/off switch.
