Abstract
Methods for identifying bridge devices and systems thereof. A bridge device receives an undefined command. In response to the undefined command, output information comprising at least one no-available parameter is generated. The bridge device sets the no-available parameter as a predetermined value. The bridge device is identified by determining whether a predetermined value of at least one no-available parameter in the output information matches a predefined value for a supported bridge device.
Claims13
A method for identifying bridge devices, comprising:
- receiving an undefined command by a bridge device from a host controller, wherein the undefined command is undefined to the bridge device or a standard interface device;
- transmitting the undefined command to the standard interface device by the bridge device;
- performing the undefined command by the standard interface device to generate output information comprising at least one specific parameter in response to the undefined command, wherein the specific parameter has an any value;
- transmitting the output information to the bridge device by the standard interface device;
- setting the specific parameter in the output information from the any value to a specific value by the bridge device;
- 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 specific 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 an undefined command;
- and
- a bridge device receiving the undefined command from the host controller, wherein the undefined command is undefined to the bridge device or the standard interface device, transmitting the undefined command to the standard interface device, and receiving output information comprising at least one specific parameter corresponding to an undefined command from the standard interface device, wherein the standard interface device performs the undefined command to generate the output information, and the specific parameter has an any value, setting the specific parameter in the output information from the any value to a specific 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 that has been set by the bridge device by determining whether the specific value of the specific parameter matches a predetermined value of a specific supported bridge device.
