The cameras use a copy of the Windows/Mac UVC driver.
Once the camera is plugged in, the OS makes a copy of this driver and stores it for use with your device. Occasionally, the computer will think that your HuddleCam is a completely different device (usually a USB hub).
To fix this, you would take the applicable driver (Windows 7, 8, or 8.1) and point your computer to look at that driver for the camera.
Here is the link for the UVC drivers.
