Everything looks fine here, I see no error messages (maybe you should
have set the device parameter: guvcview --device=video1 --verbose).
Do you have any other usb devices connected to your system besides the
integrated webcam?
If so, try disabling them, if you could also disable the integrated
webcam (maybe in BIOS) it would be great.

Paulo
