Problems solved by technology

However, in many use cases, USB storage devices are often removed from the host system without warning. If there is still data being transferred between the host system and the USB storage device at this time, this sudden removal operation often causes The data in it is lost or damaged, and in more serious cases, it may even cause the files of the host system or USB storage device to be damaged and become unusable

Abstract

The invention discloses a portable device with a reciprocating type detection terminal and a detection and control method thereof. A detection terminal is arranged at the position of a connector; when the portable device is inserted into a host system, the detection terminal is pushed to generate signal changes, so that a controller in the portable device executes a device instruction according to the signal, or when the portable device is removed from the host system, the detection terminal is pushed to change the signal until the portable device is separated from the host system completely, and the controller executes a device instruction which is set additionally by utilizing the time of several milliseconds, so that the portable device has diversified computer control and provides a power-off protection mechanism of data transmission.

Description

technical field [0001] The present invention relates to a portable device and a system control method, in particular to a portable device with an insertion / extraction detection terminal, when the detection terminal is actuated, a custom command is executed and aimed at A control method performed by plugging / unplugging a portable device. Background technique [0002] After the portable device on the market is connected with a host system such as a personal computer, data transmission and storage between the portable device and the host system can be performed. Taking a universal serial bus (USB) storage device as an example, its hot-swappable feature on the host system makes the USB storage device used as an external portable storage device widely used. Usually, for such an external storage device, the host system can use a specific device removal program to stop all future memory write operations, so as to ensure that the external storage device is removed from the host sys...
