Let me start off by saying I've searched the hell out of this issue and tried a couple solutions. I'm not posting here because I'm too lazy to figure it out myself. You guys are my last hope. Here goes: I plug my Vivid (running the latest software) in to my 64 bit Win 7 PC, but nothing happens. My phone charges, but windows does not see it. It doesn't even have the pop up that says it doesn't recognize the device. I have USB debugging enabled (it doesn't work when disabled, either), and I've tried every connection type (including htc sync mode and Disk Drive), and I have the box checked that's supposed to ask me what connection I want whenever I plug it in. Again, nothing happens but the charge. I downloaded some drivers, but it doesn't come with an exe. The only way I know to manually install the drivers requires me to first find the device in device manager. I don't know how to find the phone in there, as no errors pop up, and none of the names look like it could be my phone. I went to the official site and downloaded, installed, and updated HTC Sync when I found out it includes the drivers. Still no success even after a reboot. I've tried multiple charging cables (not the cheap ones, but the ones you get when you buy the phone) in every USB port, and still no luck. I really tried to figure this out but I've run out of ideas. I turn to you in desperation, PLEASE HELP SOLVED! I guess some of the cables are ONLY able to charge. I popped in a Kindle charger that I know can transfer data and plugged it into my phone and it worked perfectly!
