News main frame will also use specific application program, call special USB device driver to realize that valid data are transmitted.This mode
Need to write different specific drivers and application programs for different operating system, can otherwise cause driver and answer
It is user using making troubles so as to normal valid data transmission cannot be carried out with the compatibility issue of program.
The content of the invention
It is an object of the invention to provide a kind of dynamic USB device data transmission method of cross-platform free drive, can avoid installing
USB device specific drivers and application program, to improve the compatibility of product.
The technical scheme is that：
A kind of dynamic USB device data transmission method of cross-platform free drive, comprises the following steps：
1.1st, USB data transmission device itself will invent USB storage device when carrying out data transmission with host computer communication, and
Using the Universal USB storage device driver of host computer communication, that realizes data transmission device exempts from drive installation；
1.2nd, USB data transmission device inside real data is mapped into virtual USB storage device file storage area, and will be real
Border data virtual into meet host computer communication file system requirement file；
1.3rd, the data transfer realized and between host computer communication is instructed by the file operation of host computer communication.
The step 1.1 is specifically included：
USB data transmission device is according to needed for the File System Specification construction virtual USB storage device that host computer communication is used
MBR table, partition boot record table, file allocation table and root directory information；Carry out data transmission with host computer communication
When, host computer communication calls Universal USB storage device driver, according to Universal USB storage device that USB-IF tissues are announced
Class protocol specification sends or receives the order related to USB storage device to USB data transmission device, carries out USB data transmission
Device enumerates communication process, and that realizes data transmission device exempt from drive installation；
The step 1.2 is specifically included：
In the data transmission procedure of USB data transmission device and host computer communication, by USB data transmission device inside real data
The physical address map of storage is the logical address of virtual USB storage device file storage area；Then, according to host computer communication text
File format required by part system, increases file format information；Then, according to USB data transmission device inside real data
And file format information amount of capacity, update the amount of capacity and void of virtual file in virtual USB storage device root directory information
Intend starting or the termination logic address information of file；By these steps, it is possible to map real data and invent communication
The file that host file system can be understood, then instructs the number realized and between host computer communication by the file operation of host computer communication
According to transmission.
Before transmission method data transfer of the present invention or in transmitting procedure, real data is carried out by AES or device
Encryption；And the file for meeting the requirement of host computer communication file system will be invented by the real data of encryption.
Compared with the prior art, beneficial effects of the present invention are：
The invention provides a kind of dynamic USB device data transmission method of cross-platform free drive, by the way that USB data transmission device is virtual
Into USB storage device, and USB data transmission device inside real data maps virtual can be solved into host computer communication file system
The file of reading, realizes the data transmission procedure that USB data transmission device moved, exempts from application program with the free drive of host computer communication.This
Inventive method avoids installation USB device specific drivers and application program, improves Products Compatibility, and it is convenient to realize, is
User is using offering convenience.
Brief description of the drawings
Fig. 1 is the schematic diagram of the dynamic USB device data transmission method of cross-platform free drive.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the invention provides a kind of dynamic USB device data transmission method of cross-platform free drive, including following step
Suddenly：
1.1st, itself is invented USB storage device by USB data transmission device when carrying out data transmission with host computer communication.Its
Master of the middle USB data transmission device according to needed for the File System Specification construction virtual USB storage device that host computer communication is used
Leader record table, partition boot record table, file allocation table and root directory information；
1.2nd, host computer communication calls Universal USB storage device driver, is set according to the Universal USB storage that USB-IF tissues are announced
Standby subclass protocol specification sends or receives the order related to USB storage device to USB data transmission device, carries out usb data
Transmitting device enumerates communication process, and that realizes data transmission device exempt from drive installation；
1.3rd, the physical address map of internal actual data storage is virtual USB storage device file by USB data transmission device
The logical address of storage region；
1.4th, real data is encrypted by AES or device；USB data transmission device is according to host computer communication file
File format required by system, increases file format information；And according to USB data transmission device inside real data and file
Format information amount of capacity, updates the amount of capacity and virtual file of virtual file in virtual USB storage device root directory information
Starting or termination logic address information；So as to real data to be invented the file for meeting the requirement of host computer communication file system；
1.5th, host computer communication is instructed by file operation, is driven using host computer communication file system interface and Universal USB storage device
Dynamic program, the Universal USB storage device subclass protocol specification announced according to USB-IF tissues realizes that exempting from and between host computer communication should
