Hello, I just got my second Pi in the mail and am having problems. I hav a Lapdock that I'm running the pi on, I power the Pi by the usb backfeed. I have a 120GB SSD connected to the lapdock hub via USB,
The problem im having is the USB hub in the Pi keeps resetting, it losing connection, kernel spits out long logs of failure to connect to devices, then it starts working again and reconnects all usb devices. My other Pi with same exact SD card and plugged into same Lapdock works just fine. I have put a fresh Wheezy install on a card to verify that it wasn't my OS setup, I still lose USB connection. I have tried without USB SSD also but same results. The only USB devices connected besides the SSD are the Lapdock internal hub, mouse, and keyboard.
I have not overclocked this Pi yet so that can be ruled out.
Any Ideas? Is this just a faulty USB chip? Or something else?
