Internal Webcam not work

[alabanana]

(Linux Mint 14, Cinnamon 1.6.7, laptop: HP pavilion dv2000)

Hi,
I am trying to make my webcam work. Yesterday, I used cheese, blue light of the webcam was on, but the captured screeen was black. Today I tried it again, nothing happened, no light, black screen.

When booting, I notice there are repeating errors "unable to enumerate usb device on port 5".

How can I fix it???
Please help!!!

My webcam is connected and disconnected continuously. Sometimes it disappears from lsusb.
I have tested using Cheese, it showed that my webcam could work for a while until it was disconnected; then it could work again...

Update: the webcam keeps jumping from uhci_hcd to ehci_hcd...
