Hi All,

I've only posted on here once before (a very long time ago) so feel free to move this thread if it's in the wrong place! I searched and haven't been able to find a solution to my problem anywhere.

Specs:
Laptop: HP Pavilion dv6700
Processor: AMD Turion 64 x2, 2.0GHz
Webcam: not sure... HP webcam, built in above the screen
OS: Vista, 32-bit

My problem:
When I move the screen, I hear the USB disconnect/reconnect sound, and sometimes am prompted with the following alert message:

This USB device can perform faster if you connect it a Hi-Speed USB 2.0 port. Click here for a list of available ports.

What I know so far:
I was able to get the screen in the perfect position so the USB connection was 'disconnected' for good. After looking in Device Manager, I was able to determine that the following two devices were completely dropping off of the list (no red X mark or anything.. took a while to figure this part out!).

Imaging Devices -> HP Webcam
USB Controllers -> USB Composite Device

I am assuming this is a hardware issue, considering it never occurs if the laptop is stationary. The webcam must be disconnecting/reconnecting physically to an internal USB port when I move the laptop screen. Also, I NEVER use the webcam. I thought disabling the USB Composite device under Device Manager would kill the USB port in question, but I'm still getting the noise/alerts.

My Question(s)
Would uninstalling the drivers for either the webcam or USB composite device help, or will this do nothing because of 'plug & play' technology? I'm thinking everytime this physically occurs I will still get the noise/alerts, even if the drivers are uninstalled.

I have considered opening up the laptop and checking out the motherboard, but I REALLY don't want to do this. If there is a way I can completely kill that USB port without opening up the laptop that would be great. Are there any workarounds besides disabling the USB sound effects?

I appreciate the help!

The issue is that if you disable the web cam, and it disconnects, it's off Device Manager. When it connects again, Windows sees it as a new device and pops up the message. Your only option without turning off all device detection is to cut the connection to the web cam from the case.

I have the same issue, except when it does disconect, it doesn't reconect anymore, only if i re-start the computer. Very ennoying for skype. If someone know what to do!


I have the same exact issue as lookandream, I've tried several solutions(drivers,bios,updates,restore...ect) seems to be a internal hardware issue, but I cant be sure without tearing apart my laptop which Im not going to do!!.. Anyone? have anything, or even a possible solution, besides sending it in for repair?

I am also having the same issue. I think it is a wiring problem with the connection to the screen though the hinge. I can get the webcam to appear on the device manager by closing the lid halfway, but then it disappears again when I open completely.

I hoping someone out there has a fix for this. I am OK with opening up my POS HP to fix this, as I am well beyond my warranty period and I'm not paying HP way too much money to fix this for me.

At least now I know why I was getting the USB warnings popping up in the past few months, I hadn't tried the webcam for awhile.
