I have a Nexus 7 2012 that is about 1 years old and I love dearly. The problem is, I can't get it to connect to my pc. I have done extensive research here, and I can't seem to find any details about this problem or steps towards solving it. It is not simply an issue of bad cables or drivers incorrectly installed, seeing as I have used the same cables on my HTC One and they have worked fine, as well as I have tried Windows 7, Windows 8, Windows 8.1 and Linux Ubuntu 13.10. There is no reaction from device manager whatsoever on any system. The nexus does not recognize that there is anything but an outlet on the other end of the cord. I do have working ADB installed on both Windows 7 and the Ubuntu setups. This may have something to do with a car charger I used a while back. I am willing to try internal repairs if that is necessary and someone has pointers, but I need to know what I am looking for.
I am a technology student who regularly does internal repairs on all manner of devices, so feel free to technical terminology if you feel the need. I should be able to follow along. Thanks for all of your help in advance.
