Equipment identification method and device

Abstract

The invention relates to an equipment identification method and device, and belongs to the technical field of data transmission. The method comprises the steps that a wake-up instruction for electronic equipment is received; event lists of a plurality of buses of the electronic equipment are obtained, wherein the event list of each bus is used for indicating equipment connected with the bus; if the event lists of the buses comprise the event list of a designated bus, the event list of the designated bus is inserted into the head of an event general list when the event general list is generated, so that Bluetooth equipment is identified first, wherein the designated bus is the bus connected with the Bluetooth equipment. According to the method, by obtaining the event lists of the electronic equipment, the event list of the designated bus connected with the Bluetooth equipment is determined, so that when the event general list is generated, the event list of the designated bus can be inserted into the head of the event general list, and when the wake-up instruction is received, the Bluetooth equipment connected with the designated bus can be identified first, the back link speed of the Bluetooth equipment is increase, and the intelligent performance is good.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a device identification method and device. Background technique [0002] Linux (like a multitasking operating system) is a free and open source operating system used in everything from mobile phones, tablets, routers, video game consoles, to desktop computers and servers, especially in set-top boxes and smart TVs It has been widely used in embedded electronic devices. At present, most electronic devices whose kernel is Linux support a STR (Suspend to Ram, suspend to memory) function, and the STR function can enable the electronic device to realize fast sleep and fast wake-up. Most of the CPU (Central Processing Unit, central processing unit) used by electronic equipment includes more than 3 USB (Universal Serial Bus, Universal Serial Bus) controllers, for example, the mstar 938 chip includes 5 USB2.0 controllers, 2 USB 3.0 controller, so that these 7 USB controllers w...

Problems solved by technology

Assuming that the Bluetooth chip is connected to the USB bus 1 of the smart TV, if other USB external devices are plugged into other USB ports of the smart TV, when the smart TV executes the STR function for quick wake-up, the order in which the smart TV recognizes the USB bus is uncertain, Therefore, the order in which the Bluetooth chip is recognized is uncertain, and sometimes the recognition order may be relatively late, resulting in a large delay in the return link of the Bluetooth controller and poor intelligence.
