Problems solved by technology

[0003] However, the existing technology cannot realize the selective standby of composite devices such as PC cameras, because the audio devices and video devices of composite devices have independent drivers
The driver of the USB audio device is a standard driver provided by Microsoft, and this driver does not support selective standby.

Abstract

This invention discloses one method to realize compound device to select wait mode, which comprises the following steps: determining compound device spare status within preset time level to change the label information of compound device; re-listing compound device to identify the compound device into single visual frequency device and to order compound device into wait status. The invention also discloses one system to realize compound device selective wait status, which comprises compound device system and compound device application system.

Description

technical field [0001] The invention relates to equipment selective standby technology, in particular to a method and system for realizing selective standby of composite equipment. Background technique [0002] Existing PC camera (PC Camera) with USB audio equipment is composite equipment, can be divided into video equipment and audio equipment two parts. When this type of computer camera is applied to a platform such as a notebook, power saving is very important. Generally, in the prior art, device power saving is realized through selective standby. The so-called selective standby means that when the relevant device has not been used for a preset period of time, the driver of the device sends an application to the host controller to enter the standby state, and the host controller checks whether the device can enter the standby state. If possible, a request to enter the standby state is sent to the driver of the device, and the device enters the standby state after receiv...
