Plug and play device redirection for remote systems

摘要

A remote access system connects a server computer with one or more client computers, where devices are connected locally at the client computers. The devices are recognized by the client computers and a device driver is provided for each connected and recognized device. A virtual driver is created at the server computer from information specific to the device, such that the virtual driver acts as an actual driver to an application on the server computer. The application through the virtual driver is able to recognize and provide commands to the connected device.

1. A method of supporting a client device, the method comprising:
receiving, at a server computer, a device notification identifying that a device is connected to a client computer, the device associated with a real device driver located at the client computer; receiving information related to the device; creating a virtual driver at the server computer based on the information; and upon detecting a device generated event notification at an application of the server computer, redirecting, by an upper level filter driver, I/O request packet (IRP) commands using I/O control (IOCTL) code from the application of the server computer through the upper level filter driver, through the virtual device driver of the server computer, to the real device driver on the client computer, wherein the upper level filter driver is located separate from the application of the server computer.
