Embodiment Construction

[0060] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0061]With the development of USB technology, external devices such as PCs and digital cameras, video cameras, and printers are connected through USB interfaces. These external devices act as the peripherals of the PC, and exchange data under the control of the PC. However, once this convenient exchange method leaves the PC, the external devices cannot use the USB interface to operate, be...

Abstract

The invention provides a mobile terminal and a method for identifying a mobile storage device. The method for identifying the mobile storage device in the mobile terminal comprises the steps of loading a drive for the mobile storage device when it is detected that the mobile storage is connected via the OTG interface; establishing a connection to the mobile storage device based on the level of the set data signal of the drive, and disconnecting from the mobile storage device when a disconnecting indication signal is received in the process of establishing the connection; increasing the signal margin, reloading the drive and establishing the connection with the mobile storage device, wherein the signal margin is the voltage difference between the level of the set driven data signal and the level of the disconnecting indication signal. The technical scheme triggers the connection process in a looping mode in the case of failure of the USB drive connection, the signal margin every time in the loop is increased, and the appropriate signal margin is found through many attempts, and the failure of the connection caused by the false judgement of the data signal as the disconnecting indication signal is avoided.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a mobile terminal and a method for identifying a mobile storage device. Background technique [0002] USB OTG is the abbreviation of USB On-The-Go. OTG (English: On-The-Go) technology realizes data transmission between devices through the USB interface without a host (English: Host). Common uses include connecting USB flash drives, keyboards, mice and other devices to smart phones through the USB interface. However, in practical applications, it often occurs that the smart phone cannot be connected to the USB flash drive normally. Contents of the invention [0003] Embodiments of the present disclosure provide a mobile terminal and a method for identifying a mobile storage device, and the technical solution is as follows: [0004] According to the first aspect of an embodiment of the present disclosure, a method for identifying a mobile storage device ...
