Abstract
In certain information handling system (IHS) environments, universal serial bus (USB) devices connected to a client are redirected to a server or other information handling system. Multiple remote sessions may be running on an IHS as well as multiple multi-server published applications within a given remote session. To make the USB devices seamlessly accessible to the user from a given session or application when a switch occurs to a new session or a new application, the USB device may be sent a reset command which acts like a plug-in/plug-out of the USB device. The USB device is then redirected to the new session or the new application. The server is notified of the reset or the re-connection of the USB device to appropriately virtualize the USB device.
Claims20
A method comprising:
- determining connection of a universal serial bus (USB) device to a client;
- notifying a proxy client of the connection;
- sending a request to a server for the USB device to be virtualized at the server;
- initiating a first remote session, wherein the first remote session is a current active remote session;
- initiating a first application, wherein the first application is a current active application;
- determining a current active mode, wherein the current active mode comprises at least one of the current active remote session and the current active application;
- detecting a change in the current active mode, wherein the current active mode is changed when at least one of the current active remote session is switched to a second remote session and the current active application is switched to a second application;
- resetting a USB device;
- sending a notification of the reset to the server;
- and
- redirecting the reset USB device as indicated by the current active mode.
A system comprising:
- a server;
- one or more processors for processing information of the server;
- a memory of the server communicatively coupled to the one or more processors;
- and
- one or more modules that comprise instructions stored in the memory, the instructions, when executed by the one or more processors, operable to perform operations comprising:
- determining connection of a universal serial bus (USB) device to a client;
- notifying a proxy client of the connection;
- sending a request to a server for the USB device to be virtualized at the server;
- initiating a first remote session, wherein the first remote session is a current active remote session;
- initiating a first application, wherein the first application is a current active application;
- determining a current active mode, wherein the current active mode comprises at least one of the current active remote session and the current active application;
- detecting a change in the current active mode, wherein the current active mode is changed when at least one of the current active remote session is switched to a second remote session and the current active application is switched to a second application;
- resetting a USB device;
- sending a notification of the reset to the server;
- and
- redirecting the reset USB device as indicated by the current active mode.
One or more computer-readable non-transitory storage media embodying software operable when executed by one or more computer systems to:
- determine connection of a universal serial bus (USB) device to a client;
- notify a proxy client of the connection;
- send a request to a server for the USB device to be virtualized at the server;
- initiate a first remote session, wherein the first remote session is a current active remote session;
- initiate a first application, wherein the first application is a current active application;
- determine a current active mode, wherein the current active mode comprises at least one of the current active remote session and the current active application;
- detect a change in the current active mode, wherein the current active mode is changed when at least one of the current active remote session is switched to a second remote session and the current active application is switched to a second application;
- reset a USB device;
- send a notification of the reset to the server;
- and
- redirect the reset USB device as indicated by the current active mode.
