Want to start this by saying I'm pretty sure this is a pc issue rather than phone issue, I've had similar problems with every android I've owned. I installed drivers through the Nexus 4 toolkit and the tutorial by thesmokingandroid, my PC doesn't even acknowledge the phone. I get the beep when it connects and disconnects but the phone doesn't show up anywhere like my computer or device manager at all. Like I said my older phones would connect most of the time but almost always randomly disconnect/connect. I feel like it's likely a driver thing, never had problems with my iPhones or other things like mouse or keyboard. Is there a way other than a clean windows install to just clean my pc of any android related things like SDK or drivers? Also it's a custom built pc with 5 ports running win7, no ports will work. I added an in tower sd hub and feel like the problems might have started around then but I'm not sure on that. Any suggestions would be nice, not being able to connect my phone is an issue with no removable memory...

edit: Wanted to add that sometimes when I only have my mouse, keyboard, and Xbox controller connected I get those little connect/disconnect beeps at random and the bubble that says this device can perform faster. I'm pretty sure my ports are 2.0 too but I'm not sure how to check that.

I having the same problem. When I'm in fastboot mode my pc doesn't show my phone but when my phone is powered on it shows up on my pc. Anyone know what I'm doing wrong?

Anyone? I'm ready to try reinstalling Windows but would really like to know if there's something a less time consuming I could try first. I can't root or anything so I'm going to have to try something soon.

Same thing happens to me a couple days ago.
My laptop recognized the phones, but it showed nowhere in Device Manager. Adb could see my phone, but as soon as I went to bootloader, my laptop said An USB port is unrecognized

SOLUTION: I use Nexus Root Tool Kit and Google NExus 4 Tool Kit to REMOVE the nexus 4 driver, everything related to nexus 4 is removed. I only used these tools to uninstall the driver, not to install them.

Then I turned off the Windows 7's Automatic Update Driver by Window Update (or some similar names). This is important, because the driver that windows install autimatically doesn't covery the Bootloader Driver. I dont remember how exactly I turned the Automatical Diver Update off. Maybe when the popup "unrecognized USB" appear, I pressed it and there was an option to do that. Or you can search google.

A link to turn the Windows 7 Automatic Driver Installation: http://www.sevenforums.com/drivers/82054-turn-off-windows-7-automatic-driver-installation.html

Restart my computer after that. THen download driver from this http://forum.xda-developers.com/showthread.php?t=2010312 ONly the driver.

THen Install it from DEvice Manager by plugging my phone again.
Finish.
