Abstract
In one general aspect, methods and devices for use with multiple communications protocols automatically determine which communications protocol to use when connected to a system bus. Signals transmitted on the system bus are monitored to determine what communications protocol the system bus is using. After determining which communications protocol the system is using, a compatible communications protocol is selected from one of several communications protocols stored in a device's memory. As a result, a user may connect a device to the system bus without having to determine which communications protocol is used by the system bus. Furthermore, suppliers may stock a single type of device that is compatible with multiple communications protocols reducing overhead associated with stocking devices. In addition, a device may be switched between systems without regard to the communications protocol of the device or system.
