In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This option enables the operation of a sysfs based
interface for query and control of the pvrusb2 driver.

This is not generally needed for v4l applications,
although certain applications are optimized to take
advantage of this feature.

If you are in doubt, say Y.

Note: This feature is experimental and subject to change.
