Re: [Spca50x-devs] Sony Visual Communication Camera VGP-VCC1

Hi,

I just noticed that the new gspcav1 driver supports the 0ac8:c002 webcam.
It even supports the correct controller (VC0321), amazing!
I guess there's no need for the windows hack anymore.... the image is
a bit fuzzier but otherwise it functions fine. the camera light works
too.
