* Name: usbhost_findclass
*
* Description:
* Find a USB host class implementation previously registered by
* usbhost_registerclass(). On success, an instance of struct
* usbhost_registry_s will be returned. That instance will contain all of
* the information that will be needed to obtain and bind a struct
* usbhost_class_s instance for the device.
*
* Input Parameters:
* id - Identifies the USB device class that has connect to the USB host.
*
* Returned Values:
* On success this function will return a non-NULL instance of struct
* usbhost_registry_s. NULL will be returned on failure. This function
* can only fail if (1) id is NULL, or (2) no USB host class is registered
* that matches the device class ID.
