USB RECOGINITION METHOD AND SYSTEM FOR PORTABLE TERMINAL DEVICE BASED ON ANDROID

摘要

The present invention relates to a method for recognizing a USB of an Android-based portable terminal and to a device for recognizing a USB of an Android-based portable terminal that can automatically activate a related interlocking application for each external device module through a single USB interface module. According to the present invention, there is provided a USB terminal recognition method between a portable terminal provided with a linked application corresponding to the following USB device module and an Android-based Universal Serial Bus Host and the USB device module, each having a separate communication stack. A connection step in which a USB device module is connected and a USB interface module having a common communication stack is connected to the portable terminal; An individual communication stack acquiring step in which the USB interface module to which the USB device module is connected is supplied with operating power from the portable terminal simultaneously with access to the portable terminal, and the USB interface module reads individual communication stacks of the USB device module; A recognition step of reading and recognizing, by the portable terminal, the individual communication stack obtained from the USB device module and the common communication stack of the USB interface module; And a linked app execution step of executing the linked application on the portable terminal based on the recognized common communication stack and the individual communication stack.
