Is the uber_surface a plugin node? Does it have a unique nodeType? If so
you can look up nodes of that nodeType.
You wouldn't want to use .diffuse in that ls lookup since it's a common
attribute shared by multiple materials. You can add your own attribute to a
shader though, like .myUberSurface, and use that to identify the shader.
Then this will return just that shader:
cmds.ls("*.myUberSurface", o=True, mat=True)
