Embodiment 1

[0032] figure 1 The implementation process 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 host device receives USB storage device removal information from the peripheral device, and generates a USB storage device removal instruction specified by the signal.

[0034] Wherein, the peripheral device is a light-sensing hole or a remote control, and when the peripheral device is a light-sensing hole, before step S101, the method further includes: when detecting that the light entering the light-sensing hole is blocked, the main device generates a The USB storage device removal signal corresponding to the light sensing hole is specifically described in the second embodiment below. In addition, the USB storage device removal signal from the peripheral device can also be sent by the user through the removal function button on the remote control. The USB storage de...

Embodiment 2

[0046] figure 2 The implementation process of the USB storage device hot-plug method provided by the second embodiment of the present invention is shown. In this embodiment of the present invention, the peripheral device is used as a light sensing hole, the main device is a TV, and the USB storage device is used. The implementation process of the USB storage device hot-plug method is described by taking the connection of the USB interface to the TV as an example, and the details are as follows:

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

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

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, device and terminal equipment for hot plugging and unplugging of USB storage devices. Background technique [0002] Hot-plugging, that is, live plugging and unplugging, the hot-plugging function allows users to complete the plugging, unplugging or replacing of external electronic devices without shutting down the operating system or cutting off the system power supply, which 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 illegal and violent plugging and unplugging without any program protection will greatly increase the failure rate of the device. When the device is damaged, it will also bring harm to the operating system. Unsafe hidden dangers, of course, such security hidden dangers also exist in sma...
