Device won't connect via USB I have a HTC G2 running Android 2.3.4 that I've recently tried to root using the guide at the XDA developer's site.  After step 3.3, the USB connection stopped working.  More precisely, when I plug the USB cable into the PC and the phone, the PC does not detect the phone (for instance, it is not in the devices manager) and the phone does not get a USB notification (though it does charge).  I've tried all the basic trouble shooting steps as outlined here, but I haven't had any luck fixing the problem.

As I see it, either one of two things has happened.  The phone's USB port needs to be replaced or I've introduced a glitch that prevents the phone from communicating with the computer.  Is there a way to find out which case I'm facing and if it's the second case, how to diagnose and fix the glitch?  Thanks
I understand your problem,Your device may not have supported  Drive and  check is it connect mass storage(memory card) or not .if you may change the setting in USB debugging,
