Method for sending a keycode of a non-keyboard apparatus

摘要

A method for sending a keycode of a non-keyboard apparatus is provided and includes the following steps. The non-keyboard apparatus determines the connection status between itself and a computer by the time required for device enumeration. Then, according to a value generated from device enumeration, the non-keyboard apparatus identifies the kind of operating system running on the computer. The non-keyboard apparatus sends to the computer a keycode corresponding to the Num Lock key and/or a keycode corresponding to the Caps Lock key such that a sending time and a feedback time are obtained. A parameter related to the efficiency of the computer is then calculated based.

1. A method for sending a keycode of a non-keyboard apparatus, comprising the steps of:
(a) connecting the non-keyboard apparatus to a computer so as to perform device enumeration and generate enumeration information, wherein the enumeration information is recorded by the non-keyboard apparatus and includes an enumeration value; (b) identifying, according to the enumeration value, the kind of an operating system used by the computer, and recording the kind of the operating system by the non-keyboard apparatus; and (c) reading the kind of the operating system so as to determine a preset second keycode that matches the kind of the operating system, wherein the second keycode is an ASCII (American Standard Code for Information Interchange) code.
