* Thread for managing usb camera hotplug. It does below: |

* 1. Monitor camera hotplug status, and notify the status changes by calling |
|
* module callback methods. |
|
* 2. When camera is plugged, create camera device instance, initialize the camera |
|
* static info. When camera is unplugged, destroy the camera device instance and |
|
* static metadata. As an optimization option, the camera device instance (including |
|
* the static info) could be cached when the same camera plugged/unplugged multiple |
|
* times. |
