Abstract
Techniques for facilitating communication between a portable media device (PMD) and an accessory via multiple communication paths. The accessory has a unique accessory identifier that it can send to the PMD upon establishing a connection via each communication path. The PMD can determine whether the same accessory is connected via multiple communication paths based on the accessory identifier received via each communication path. The PMD can route information to the accessory and control routing of information from the accessory based on the set of communication paths that are currently connected and can dynamically change the routing as communication paths are connected and disconnected.
