Combining redirected usb interfaces into a single composite device

A method for combining multiple redirected USB interfaces into a single composite device, the method comprising:

• receiving, by an agent on a server, a plurality of device arrival notifications, each device arrival notification including device information pertaining to a redirected interface of a composite device;
• detecting, for each device arrival notification, the presence of an interface hint in the device arrival notification;
• and
• generating composite device information that includes the device information from each of the device arrival notifications such that the composite device information defines each of the interfaces as interfaces of a composite device on the server.

One or more computer storage media storing computer executable instructions which when executed in a computing system implement a method for combining multiple redirected USB interfaces into a single composite device, the method comprising:

• detecting, at a client-side proxy, that a plurality of interfaces of a composite device are to be redirected to a server;
• creating, for each of the plurality of interfaces, a device arrival notification that includes a device descriptor having a device class field that is assigned a class code of the interface;
• adding an interface hint to each device arrival notification, the interface hint identifying an interface number of the corresponding interface within the composite device;
• sending the plurality of device arrival notifications to an agent on the server;
• in response to detecting the interface hints included in the device arrival notifications, creating, by the agent, a new device descriptor that includes a device class field that is assigned a class code representing a composite device and an interface descriptor for each device arrival notification, each interface descriptor being assigned the class code of the corresponding interface.
