Abstract
Methods, systems, and apparatuses are described for identifying devices coupled a media device hub. A device map in the media device hub may create a map entry that associates a first device, a port to which the first device was at least previously coupled, and a first key of the first device. A second key is obtained from a media device that is coupled to a current port of the media device hub. A determination is made whether the second key is the same as the first key stored in the device map. If the first and second keys are the same, a determination is made whether the current port to which the second device is coupled is different than the port indicated in the device map. If the current port is different than the indicated port, the device map is updated to indicate the first device as coupled to the current port.
