笔记本电脑车载摄像头无法正常工作并充斥了dmesg

I have an issue with my internal camera, it doesn't work anymore. I used it a few times without any issue before, but recently it stopped working. I disabled uvcvideo as it prevented some apps using camera to work (even without using the video). My dmesg output is flooded with these messages :

[15790.697055] usb 1-13: Product: HD Webcam [15790.697056] usb 1-13: Manufacturer: SunplusIT Inc [15790.697056] usb 1-13: SerialNumber: 01.00.00 [15790.700414] usb 1-13: USB disconnect, device number 39 [15791.080408] usb 1-13: new high-speed USB device number 40 using xhci_hcd [15791.180878] usb 1-13: New USB device found, idVendor=04f2, idProduct=b68b, bcdDevice= 0.07 [15791.180879] usb 1-13: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [15791.180880] usb 1-13: Product: HD Webcam [15791.180880] usb 1-13: Manufacturer: SunplusIT Inc [15791.180881] usb 1-13: SerialNumber: 01.00.00 [15791.184280] usb 1-13: USB disconnect, device number 40 [15791.564440] usb 1-13: new high-speed USB device number 41 using xhci_hcd [15791.664853] usb 1-13: New USB device found, idVendor=04f2, idProduct=b68b, bcdDevice= 0.07 [15791.664855] usb 1-13: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [15791.664855] usb 1-13: Product: HD Webcam [15791.664856] usb 1-13: Manufacturer: SunplusIT Inc [15791.664857] usb 1-13: SerialNumber: 01.00.00 [15791.668066] usb 1-13: USB disconnect, device number 41

看起来它一直保持连接和断开连接一次又一次。启用uvcvideo时,我还有其他错误消息:

有什么我可以做的,还是我的相机突然坏了?
