Okay, so we don't need the 360 brand of wireless adapter. Aftermarket works, correct?
So I wonder if the same holds true with webcams. UNO is the first software that has been released that supports cameras. Has anybody tried a usb camera to see if UNO recognizes it? I don't have one so I can't try it.
Wrong. The third party wireless adapters connect to the ethernet port. Since ethernet is a standard any third party adapter will do.
Since the camera connects to the 360 via USB, it needs drivers. And the drivers are contained in the OS (via latest dashboard update). If you try plugging any ol' USB device that connects to the OS, you won't get anything. Only the things they allow will be detected.
It IS possible that someone may find a webcam that can have it's firmware updated to match it, but don't expect that anytime soon.
