Testimonials

SimbirSoft Ltd has participated in ACS Motion Control Ltd’s pilot project and was selected as one of the sub-contractors for developing different components under the unified environment of the Next Generation MMI project based on modern UI design and latest Microsoft .NET technologies. Since this would involve an extended period of cooperation, we anticipated a professional, well-organized and experienced team of software developers guided by an assertive team leader with whom we could establish simple and clear relationships along with planning and team management processes of high quality. The main evaluation criteria of the pilot project was the ability of the sub-contractor to successfully complete the project within the given timeframe and budget, by exactly following our development process. And we're very glad to say that our cooperation with SimbirSoft’s team has fully lived up to our expectations and the project was a complete success. We're pleased with the product quality and the team's attitude both to the development process and to the final product itself. We're going to continue our collaborative work in the upcoming projects and would recommend the team to the others looking for professional team of software developers.

USB over IP (USBIP)

USB over IP provides users with local access to USB devices connected to remote computers. With the special derives developed by our specialists the user can work with any USB devices connected to any network computer as if it’s connected to his PC.

Customers:
 A leading enterprise systems management vendor.

Industry sector:
Microelectronics, IT

PROBLEM:

The task was to enable local network users to access any USB devices connected to remote computers. It was necessary to work out a solution for Windows Terminal Server clients which would allow the clients to use the USB devices as network server device. The existing similar projects do not comprise their interaction with Terminal Server or have significant restrictions.

SOLUTION:

There is an open source project USBIP (http://usbip.sourceforge.net/) solving the problem for Linux OS. The project USBIP was based on the similar software architecture: USB data packets are encapsulate into TCP/IP packets and then transmitted between the server and the client.

General description:

The software solution for Windows OS consists of the following components:

  • USB filter driver. It is located in the driver stack of the client’s OS above the device driver. With the help of client application requests it allows redirecting all the device requests to the external application.
  • USB virtual Host (Bus) Driver is a bus-line. The virtual USB devices are connected to it. It is managed with an external user application.
  • The user application which manages the USB filter driver and enables the interaction via network protocol. Thus, the user application performs functions of a client and ones of a server (provides the access to the devices connected to its computer and seeks the access to the remote devices).
  • External dynamic library with Virtual Channel technology to realize it in Windows Terminal Server.

Platform:
Windows 2000, Windows XP, Windows Vista

Main technologies and libraries used:
Ñ++, WinApi, Windows DDK
