Correct - the Windows drivers for the Microsoft USB cameras know how to configure the Microsoft hardware correctly. So on a Kangaroo running Windows it is likely no issue.
Much like this custom driver for the PS3 Eye:

However most of the video capture related software in use on the Linux RoboRIO depend on V4L's ability to configure said cameras (GRIP uses OpenCV which uses V4L). As Billbo911 has demonstrated above - on a bunch of models of the Microsoft cameras it doesn't work like you would expect. The
V4L project is the core common solution to USB webcam support for Linux systems. If that doesn't work for a particular camera it either needs to be addressed there
or a lot of development work would need to happen to create another framework unique to a camera. Course a brighter light or tinted lens as a hack works as well.
