Like Terebacca, I also reached a stage where most things on my Linx 810B were ok apart from the camera. I spent a great deal of time finding a solution as below. It works in Skype and with the camera app.
See the GoogleDrive link for the 2 drivers which require updating. ( Intel(R) AVStream Camera and Camera Sensor Unicam ov2680 )
There is also a README file with full instructions. Please post back successes or failures.
