Micro usb port

I was having issues with my appletv 2g after an update. The system froze at the apple logo so I did not have access to the menu items for a reset. I pulled the power cable and plugged it back in and no dice. I then used my micro usb cable from my kindle to connect to itunes and restore. This process worked fine and apple tv is up and running. The problem is the micro usb cable no longer powers on the apple tv. Thought it was my cable but I tried a new cable and nothing. Tried new computer, nothing. Has apple purposely deactivated the micro usb port in this last update and if so how do we fix it? If you update through the appletv menu you should be fine but I would not recommend an itunes restore using a micro usb right now.
