Ok, I have a 2012 xB and when I plug into my USB and start the car my phone will charge up but not connect to the system. When I go to the system the USB icon is dark. When I plug in my interior lights they start up but not stay on. Anything I'm not seeing here.

 

I know on a PC I had once, it was possible to overload a USB and it would be disabled until the next re-boot?

Maybe?
