Accessory detection system
First Claim
1. A system for interfacing a communication device with an accessory, comprising:
- the communication device comprising;
a memory configured to store at least a portion of control software code, patch, or update;
a processor configured to utilize the control software code, patch, or update to interface with the accessory;
a communication device interface configured to connect the communication device to the accessory to thereby receive at least a portion of the control software code, patch, or update from the accessory and store at least a portion of the control software code, patch, or update in the memory;
the accessory comprising;
a non-volatile memory configured to store the control software code, patch, or update and an accessory version ID,a controller configured to interface with the memory;
an accessory interface configured to connect the accessory to the communication device and send at least a portion of the control software code, patch, or update to the communication device.

Abstract
A method and apparatus for interfacing an electronic device and an accessory is disclosed. In one embodiment the accessory comprises a communication device. To achieve desired operation of the accessory with the communication device the accessory includes memory configured to store control data or other interface data. Storing the control data in the accessory insures that the communication device has access to the control data tailored to the accessory hardware. Storing the control data on the accessory also creates independence between the accessory an the electronic device such that accessory may be introduced to market after the communication device is purchased. In one embodiment the control data is downloaded to the communication device for use by the communication device. The communication device may permanently store the control data such that the download process may be avoided during subsequent use of the accessory with the communication device.
