The integrated 'Exmor'-based webcam on my Sony VAIO VPCF22KFX laptop is no longer recognized by the OS. Under Windows 7 64-bit, the webcam worked flawlessly. Sony's web site reports this laptop model as Windows 8-ready. When I upgraded to Windows 8, it was recognized about 50% of the time after booting up under Device Manager >Imaging devices >USB2.0. After a few days, it stopped showing up altogether and cannot be found either when the Device Manager's 'hidden' option is selected. I went through uninstalling the unrecognized device, re-upgrading the OS,, single-patch updates from Sony, etc., but the result is the same. Sony does not explicitly publish a Windows 7 or Windows 8 driver for the webcam itself.

From what I observed, the webcam was relying on the generic USB2.0 that showed up under 'Imaging devices'. For whatever reason, that entry no longer shows up. The webcam worked fine under Win7 64-bit and about half the time under Win8. Sony hasn't ever explicitly published a driver for the webcam on this model.

They have published a driver installer supporting USB 3.0, among other hw, but that's it. My take is that Windows 8 doesn't provide the generic driver component(s) anymore and Sony is playing catch-up at the moment. I did pose the question on Sony's support community site, but, alas, they're in a transition to a new site that will go online on Nov 19. Thus, my post here. Sony support gives 15 minutes of initial troubleshooting, but then contend they have to charge almost $80 for continued support, even though they confirm on their web site that the specific model is Windows 8-compliant. My laptop is still under Fry's support warranty, but I'd rather not ship my laptop for a fix is more than likely is related to a driver or configuration issue.
