What about the Android phone USB doesn't connect to the computer?

A, mobile phone USB can not be connected to the computer because the phone is not installed driver, can download pea pods and other software to drive installation.

Two, the second mobile phone USB not connected to the computer solution without installing anything, you put your mobile phone connected to the computer, click the phone settings-application-development--USB debugging hook, the phone has a "turn on the USB function" hint, the point is OK.

The handset USB interface power supply is insufficient may first the battery charge good electricity to connect the computer, but this is too inconvenient. Let the phone in connection with the computer's instant USB interface power supply is not less than the phone's electricity consumption, so in this moment should be "USB interface power supply sufficient." How to do it? Of course, the small series can not change the USB interface power supply, you have to change the mobile phone consumption. Small part of the specific approach is to close all processes, turn off the phone screen, and then connect the computer, in short, reduce the phone power consumption on the line. I am not sure that every friend will succeed in using this method, but at least my starting point is good, that is, I hope to be able to bring help to friends with this problem.
