Worked like charm in my Asus T101 MT running 10.8.1. Now my cam is recognized as built-in iSight.
It was already recognized before, and it worked well with all video programs except for the fact the image is flipped upside down, which is unrelated with the way the system recognizes the camera. I wanted to make it iSight, so iGlasses worked with it and help me to put the output of the camera in proper position. Didn't work: even with the fix, when i chose iGlasses as the camera, the programs either crash or stop outputting anything (and the camera indicative blue led turns off). I think now the problem is QE/Ci related - my netbook relies on an Intel GMA3150, which is yet unsupported, for graphics.
As a side note, the vendor/product ids of my cam differed only by a single digit in the vendor line from the ones who came with the kext. Maybe that explains it was so easy, without any of the problems reported here (lost of sound, etc).
Many thanks to Andy Vandjick, who made this kext and shared it with us, and to Oldnapalm, who clarified where exactly we should edit the plist.
