Bug reference: https://bugs.launchpad.net/bugs/1168430 monitor webcam not detected (intermitent) [IMPACT] This model-specific quirk fixes an observed Raring regression from 12.10. Some models of OmniVision webcam need a pre-existing quirk in order to avoid a condition which prevents the driver from recognizing the harware consistently. Some timing difference between 12.10 and Raring exposed the problem for this particular OmniVision model, which wasn't in the quirk list. [TESTCASE] Bug reporter confirms that adding this model to the quirk list fixes the problem, allowing the webcam to be consistently recognized in Raring. [Regression Potential] Very low risk: This patch affects only this particular machine and webcam model, and only inhibits the query for a feature which this webcam doesn't support anyway.
