Embodiment 1

[0032] figure 1 The implementation flow of the USB storage device hot plug method provided by the first embodiment of the present invention is shown, and the details are as follows:

[0033] In step S101 , the master device receives the USB storage device removal information from the peripheral device, and generates a removal command of the USB storage device specified by the signal.

[0034] Wherein, the peripheral device is a photosensitive hole or a remote controller. When the peripheral device is a photosensitive hole, before step S101, it also includes: when it is detected that the light entering the photosensitive hole is blocked, the main device generates a The USB storage device removal signal corresponding to the optical sensing hole is specifically described in the second embodiment below. In addition, the removal signal of the USB storage device from the peripheral device can also be sent by the user through the removal function button on the remote control. The US...

Embodiment 2

[0046] figure 2 It shows the implementation process of the USB storage device hot plug method provided by the second embodiment of the present invention. In the embodiment of the present invention, the peripheral device is used as a photosensitive hole, the main device is a TV, and the USB storage device The implementation process of the USB storage device hot-swapping method is illustrated by connecting the USB interface with the TV as an example, as follows:

[0047] In step S201, when the light entering the light sensing hole is blocked, the television generates a USB storage device removal signal corresponding to the light sensing hole.

[0048] In the specific implementation process, a corresponding photosensitive hole can be set near each USB port of the TV. When the user needs to remove the USB storage device, block the light that enters the corresponding photosensitive hole of the USB storage device with hands or other objects. light, the light sensing module corresp...

Embodiment 3

[0059] image 3 It shows the implementation flow of the USB storage device hot plug method provided by the third embodiment of the present invention. In the embodiment of the present invention, the peripheral device is a remote control, the main device is a TV, and the USB storage device is The interface is connected with a TV as an example to illustrate the implementation process of the USB storage device hot-swapping method, which is described in detail as follows:

[0060] In step S301 , the television generates a removal command of the USB storage device according to a USB storage device removal signal sent by the user through the remove function button on the remote controller.

[0061] In the specific implementation process, a USB storage device safe removal function button is provided on the remote control of the TV set, which is used to send a USB storage device removal signal to the TV through infrared rays, and a detection module is set in the bottom drive module of ...

Abstract

The invention is suitable to be applied to the field of electronic techniques, and provides a hot-plugging method, a hot-plugging method apparatus and a terminal device for USB (universal serial bus) storage devices, wherein the method comprises the following steps that: a main device receives a USB storage device removed signal from a peripheral device, and generates and executes a removed instruction of a USB storage devices designated by the signal. By using the method, device and terminal device provided by the invention, the problems that the existing hot-plugging method for USB storage devices is complicated in operation process, and because of the presence of illegal violent removal behaviors, the hot-plugging method is low in convenience and poor in flexibility, hardware devices and data are easy to be damaged, and the safety of stored data and the stability of an operating system of the terminal device can not be guaranteed are solved, the more convenient and flexibility of the hot-plugging method for USB storage devices are improved, the damage probabilities of hardware devices and data are reduced, and the safety of stored data and the stability of an operating system of the terminal device are improved.

Description

technical field [0001] The invention belongs to the field of electronic technology, and in particular relates to a method, a device and a terminal device for hot plugging of a USB storage device. Background technique [0002] Hot-swapping, that is, hot-swapping, the hot-swapping function allows users to complete plugging or replacing external electronic devices without shutting down the operating system or cutting off the system power supply. This function improves the convenience of users , while improving the scalability and flexibility of the system. However, while hot-swapping brings convenience, it also has certain hidden dangers. Long-term direct and illegal violent plug-in without any program protection will greatly increase the failure rate of the device, and damage the device will also bring harm to the operating system. Unsafe hidden dangers, of course, such hidden dangers also exist in terminal equipment such as smart TV platforms and computers. Frequent illegal...
