A&B Software ActiveUSB


The A&B Software ActiveUSB is a universal USB3 Vision Driver and hardware-independent SDK designed to provide developers with rapid access to USB3 Vision digital cameras. Just drop an ActiveUSB control onto the surface of your application and have it immediately support multiple USB 3.0 cameras. With the A&B Software ActiveUSB, your application does not have to rely on a specific camera model – any USB3 Vision™ compliant camera will work with it out-of-the-box in any popular development environment, such as Visual Studio, Visual Basic (VB), Delphi, PowerBuilder, Java, Matlab, Python. You can even insert an ActiveUSB object into an MS Word or PowerPoint document and have the live video embedded right into your presentation!
