Abstract
In accordance with certain aspects of the automatic protocol determination for portable devices supporting multiple protocols, a portable device detects which one of the multiple protocols is being used by the host device for subsequent communication with the portable device. This detection is based on the content of a command received from a host device. The detected protocol is then used by the portable device for subsequent communication with the host device. The host device may also send, to the portable device, a notification of which of the multiple protocols is being used by the host device.
