HP Envy 14-1110nr Notebook PC
Window 7 64 bit Home Premium
A few months ago I started getting random hard restarts while I was on my computer. Around this time I discovered that when tipping my screen back a bit, a usb disconnect noise sounded from my computer. I was able to determine that the disconnect noise was coming from my web-cam, so I disabled the driver, and since, no noise.
But the hard restarts continued. Eventually they started being replaced by blue screen errors stating BUGCODE_USB_DRIVER. A little bit of investigation let me to discover that the actual problem is a USB timeout, likely associated with usbhub.sys.
Just this week I decided to do a clean install of my operating system. Within a few minutes, even before installing any drivers, the computer crashed with the same error. I updated each driver I could, and updated the BIOS, but still no luck, I got two crashes this morning.
The crashes occur at random times, with seemingly no cause. It occurs both when I am using the computer and when I am not. It occurs when I have done a fresh restart and when it has come back from hibernation or sleep. It occurs when I have usb devices attached and power attached or when nothing is attached.
I can attach the minidump files if it would help, but I don't think much info will be gained from it.
I'm at the end of my experience with this problem. Please let me know if there is anything I can do to help figure this out. Thanks.

Sooooooo yeah. Still waiting on any help I could get.
I'll put my BlueScreenView screenshot up if that makes a difference. For some reason my computer won't let me zip up my minidump files, so I'll leave it at this for now...

For anyone interested: The problem has sorted of slowed down to being non-existent. To me, this definitely spells hardware issue. I think what happened was a wire connecting the web-cam to the laptop through the screen joint got caught in between being disconnected and connected, probably by my daughter pulling back on it while it was open.
Since this is a USB device it would cut out randomly and give the error.
I think it has stopped because it wiggled itself out of the slot more to be just disconnected altogether. This is just speculation, though. I was thinking about opening it up to take a look, but since I haven't seen the error in a long time, there's no reason to.
Hopefully this helps.

So, I had this exact same problem for a couple of months. I would get random Bluescreens or hard freezes, with all the crash files pointing to some sort of USB problem. I would also get the USB connect/disconnect sounds when moving my laptop screen.
I finally opened up the entire unit, took the screen off the hinges, took the screen out and lo and behold, behind the screen the connector for the webcam/mic was out of its port. I popped it back in and all is well! Opening up the whole thing wasn't super easy but if you're good with a small screwdriver, it's totally possible. There are guides all over the web, try notebookreviews envy forum as well as the official HP Envy 14 disassembly guide.

I think you are all right. I need to find this cable and try to reseat, but I've had the same symptoms. I wiggled the lid and I get the USB sound. I'm so thankfull for your postes. HP needs to create an FAQ for this problem, because I thought I had one of the USB ports going bad or soldering breaking loose from the board. I'll amend this post if the web cam cable ends up being the cause.

Thanks akashhhhh for the hint with the connector! I had the same problem of frequent BSOD with an envy 14-1000sg, it would randomly crash when the display was moved. I followed the service guide and took apart the whole unit. I found that the connector was sitting loose and fixed it with superglue, and rearranged the tape holding the cable.
I think the disassembly of the whole unit was actually unneccessary. Just prying apart the display case around the webcam should be enough I believe. Thanks again for the hint towards mechanical failure, I had already tried everything else software-wise!
