Abstract

The invention provides a USB (universal serial bus) peripheral processing unit, comprising a processor, an upstream USB interface, a downstream USB interface, a status recognition unit, a data selector, a file management control chip and a bus conversion chip. The processing unit is characterized in that the upstream USB interface is used for being connected with a host machine; the downstream USB interface is used for being connected with a USB peripheral; the status recognition unit is used for detecting insertion and removal of the USB peripheral connected with the downstream USB interface and transmitting insertion or removal information of the USB peripheral to the processor; the data selector is used for connecting or disconnecting the upstream USB interface and the downstream USB interface under the control of the processor; the file management and control chip is used for operating the file system of a USB mass storage facility under the control of the command transmitted through the internal bus when the downstream USB interface is connected with the USB mass storage facility; and the bus conversion chip is used for converting the USB bus of the upstream USB interface into an internal bus.

Description

technical field [0001] The present invention relates to Universal Serial Bus (USB) technology, and more particularly, the present invention relates to a USB peripheral device processing device, wherein the USB peripheral device processing device can determine the type of the connected USB peripheral device and according to Different processing methods are adopted for the pre-defined rules. Further, the present invention also relates to a processing method for a USB peripheral device. Background technique [0002] Universal Serial Bus (USB) is a standard interface with low price and superior performance. At present, peripherals that support USB interface are very common, such as mouse, keyboard, tablet, game joystick, U disk, etc. Mobile hard drives, digital cameras, MP3 players, printers, scanners, cameras and USB-Keys, etc. [0003] In computer applications, for the consideration of information security, it is desirable to adopt different strategies according to the types ...
