Background

At present, a cloud computing technology is widely applied to scenes such as scientific research and teaching, medical treatment, government affairs and office, a cloud desktop is taken as an example, the principle is that a virtual machine instance runs on a cloud server for each user, and a terminal is connected to a desktop of the cloud virtual machine through a remote desktop transmission protocol to perform interactive operation. However, the traditional remote desktop transmission protocol can only redirect the operation of a keyboard and a mouse on the terminal, and cannot identify and read the USB peripheral on the terminal, and when the terminal is accessed to a cloud desktop, the local USB equipment of the terminal cannot be used on the cloud desktop;

under the trusted and creative trend, a large number of government units adopt a domestic alternative scheme, use the terminals of domestic chips to combine with the domestic desktop system of linux kernel to carry out daily work, and complete service migration transition through a cloud desktop or cloud application technology;

chinese patent application No. CN102710734A discloses a computer remote control system, which comprises a controlled terminal box and a control terminal box, wherein an electronic circuit board and a GPRS module are installed in the box body of the controlled terminal box, the box body is provided with an interface which can be connected with a keyboard interface, a mouse interface and a display card of a controlled computer host, an interface which is connected with a display interface and a power interface, a circuit formed by the electronic circuit board and the GPRS module is provided with an input processing module, a data processing module, an output module, a test module, a control module and a transmission module, and the box body of the control terminal box is internally provided with a GPRS module which is connected with a serial port of the control terminal computer host. The system can send the image of the computer display of the controlled end to the control end and send the keyboard and mouse commands of the control end to the controlled end, does not depend on computer software and network, and is convenient and reliable to control; however, the invention can not enable USB equipment (such as a U disk, a printer with a USB interface, a scanner, a UKEY and the like) accessed on the terminal to directly identify and drive in a cloud desktop or cloud application, thereby restricting the use of the existing peripheral equipment in a domestic substitution scheme, and if the printer and the UKEY can not be used in a business system of a government organization, the work is seriously influenced.

Therefore, there is a need for an improved USB device remote read/write system to solve the above problems.
