on device manager it shows under imaging devices

On the My Computer properties window, click on the Hardware tab, and then click Device Manager.
Click on the plus ( +) sign next to Imaging Devices and locate the webcam item in the device list.
If the webcam is not listed, do the following activities to install the driver using the webcam driver recovery.
Click Start, click All Programs, click PC Help & Tools, and then click HP Application Recovery.
Select Driver installation and click Next.
Select the HP Webcam 1000 driver from the list, and click Install.
If the webcam is listed under Imaging Devices but there is a red X on the icon, the webcam is disabled. See figure below.

Try reloading your webcam drivers. If you enter your device manager, look for imageing devices, if it is being seen by the unit, you may have a software problem.
Try, quickplay and see if you show it their.

It sounds like a missing driver. That is probably why it tells you that no device has been detected. Try reinstalling the driver for it.

Ok, since I figured it out I will answer my own question for others' sake.

Webcam does not show up under "imaging device" in the device manager.

It does show up under USB controllers.

Right click on webcam and update driver.

Click Browse my computer....
Click Let me pick from a list....
Select "USB Composite Device"

Voila. Works in Quickplay, Skype, etc.
