Abstract
Safe mode operation for portable devices supporting multiple protocols includes a portable device that supports multiple protocols, such as a base functionality protocol and an enhanced functionality protocol, reporting to a host device that the portable device supports only a single protocol (e.g., the base functionality protocol). This single protocol will be used for subsequent communication between the host device and the portable device. This reporting to the host device that the portable device supports only a single protocol can be triggered, for example, by an appropriate button(s) on the portable device being pressed when the portable device is powered on.
