Abstract
An authentication controller coupled to a first communication port of a portable media device is allowed to provide authentication on behalf of an accessory device coupled to a second communication port of the portable media device. In one embodiment, a cross transport connector includes a connector configured to couple with an accessory and a connector configured to couple with a portable media device such that the accessory can be coupled to the second communication port of the portable media device. The cross-transport connector also includes an authentication controller. The authentication controller may request authentication from the media device over the first communication port of the portable media device. The request may also include an identifier of the second port, to which authenticated permissions obtained via the first port may be transferred.
