Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0024] The idea of ​​the present invention is: when the portable computer is connected to the computer through a USB cable, judge the current working mode of its own USB driver, if it is in the normal working mode, then the portable computer is connected to the computer through the ACTIVE SYNC software, and performs data exchange , if it is a portable mobile hard disk working mode, then the portable computer establishes a connection with the computer through the USB driver of the existing portable mobile storage device mode, and after changing its own attribute information, it exchanges data with the computer as a portable mobile storage device.

[0025] figure 2 Shown is the system software block diagram of the portable computer applying the present invention. The USB client controller of the portable comp...

Abstract

This invention provides a method to realize the data interchange between the walk computer and computer with two working modes, that are normal mode and portable memory working mode. When the USB driving program is in normal mode, then the walk computer is connected with the computer through software ACTIVE and SYNC for data exchange. When USB driving program is in portable memory working mode, then the walk computer is connected with the computer through portable memory USB driving program for data exchange between the portable memory device and computer.

Description

technical field [0001] The invention relates to the technical field of computer peripheral equipment, in particular to a method for realizing data exchange between a portable computer and a computer. Background technique [0002] With the development of embedded technology, more and more portable computer products are used, such as portable computers with POCKET PC (PPC, an embedded operating system developed by Microsoft for mobile devices) as the operating system, or SMARTPHONE ( An embedded operating system developed by Microsoft for mobile devices) has been widely used as a portable computer operating system. [0003] Existing portable computer usually uses following two methods to carry out data exchange with computer (PC), and this computer can be desktop computer also can be notebook computer etc. [0004] Method 1: Use the synchronization software (ACTIVE SYNC) to realize the data exchange between the portable computer and the PC. When applying this method, as fig...
