Supported UVC Resolutions
The USB 2.0 UVC (Universal Video Class) video driver resolution table is basically an internal list of resolutions
available for the Host PC and the Camera to negotiate and use for a specified application. Typically, the highest
resolution possible between both the PC and camera is used. However, not all OS and application combinations
are typical. Some applications are assigned to a lower value, or the lowest resolution to purposely minimize the
bandwidth requirement. In order to avoid selection of the smallest resolution possible, the resolutions of 160 x
120 and 160 x 90 were removed from the camera due to the selection of the lowest resolution by some UC
Clients and because it looked sort of wicked awful (in some respects).
