Abstract
Methods for identifying bridge devices and systems thereof. A bridge device receives a standard command. In response to the standard command, output information comprising at least one no-available parameter is generated. The bridge device sets the no-available parameter in the output information as a predetermined value if a command code or at least one no-available in the standard command matches a predefined value. The bridge device is identified by determining whether a value of the no-available parameter in the output information matches a predetermined value corresponding to a supported bridge device.
Claims14
A method for identifying bridge devices, comprising:
- receiving a standard command comprising a command code by a bridge device from a host controller, wherein the standard command is recognized and defined to the bridge device;
- transmitting the standard command to a standard interface device by the bridge device;
- performing the standard command by the standard interface to generate output information comprising at least one no-available parameter in response to the standard command, wherein the no-available parameter has an any value, and transmitting the output information to the bridge device by the standard interface device;
- determining whether the command code matches a predefined value by the bridge device;
- setting the at least one no-available parameter from the any value to a specific value by the bridge device if the command code matches the predefined value;
- transmitting the output information that has been set by the bridge device to the host controller by the bridge device;
- identifying the bridge device by the host controller or an application according to the output information that has been set by the bridge device by determining whether the specific value of the no-available parameter matches a predetermined value of a specific supported bridge device.
A system for identifying bridge devices, comprising:
- a standard interface device;
- a host controller transmitting a standard command comprising a command code;
- and
- a bridge device receiving the standard command from the host controller, wherein the standard command is recognized and defined to the bridge device, recording a command code therein, transmitting the standard command to the standard interface device by the bridge device, and receiving output information from the standard interface device, wherein the standard interface device performs the standard command to generate the output information and the output information comprises at least one no-available parameter, and the no-available parameter has an any value, determining whether the command code matches a predefined value, and setting the at least one no-available parameter from the any value to a specific value in the output information if the command code matches the predefined value, and transmitting the output information that has been set by the bridge device to the host controller,
- wherein the host controller or an application identifies the bridge device according to the output information by determining whether the specific value of the no-available parameter matches a predetermined value of a specific supported bridge device.
