I am trying to resolve this USB issue on a HP Pavilion zv6000 laptop. For some strange reason, everytime you insert ANY USB device into ANY USB Port, the computer will completely lock up. The only thing you can do is do a hard restart. What's even more funny is if you leave the device in the port while starting up the laptop, Windows will not boot. There are no error messages, it just locks up at the Windows black screen that shows the progress bar loading. I have taken a look in the device manager to see if there was anything strange in there, but there isn't. I have completely uninstalled the USB Root Hub from Device Manager while in Safe Mode, and then let Windows reinstall it in normal mode when I restarted. That did not resolve the issue. I have tested all 4 of the USB Ports (2 left, 1 right, 1 rear). Fails every time. The furthest I got once was the hardware installer icon by the clock one time, and I think that came up when I quickly inserted and removed the USB Device (presently testing it with a flash drive). Currently I am running sfc /scannow hoping that may find something, though I am not hopeful. Is there anything else that I can try to resolve this issue? Edit: **NOTE** - sfc /scannow did NOT fix the issue.
