What did Velleman support say about this?
</div>


<div>
<div class="content wysiwyg-content">
I use USB relay boards (manufactured by Velleman) on our bespoke retail system and they install to a virtual COM port and have worked like a charm on various pcs / with Visual Basic / VBA for some years. I have these installed in 8 premises without a problem on Windows 7 &amp;&nbsp;8.1 machines.<br />
<br />
The latest batch of PCs we've purchased are Windows 10 of course which didn't seem like a problem but now I've found that although the serial port shows in device manager as expected, and I can <i>control </i>the board as before, I cannot seem to get any input from the port. Normally when I press a button on the board, a data packet is received but now there is nothing. Without looking into the driver software, is there any Windows 10 reason anyone knows of which might block such input for example?<br />
<br />
Any thoughts most welcome, thanks.

Windows 10 USB / Serial Port Problem

Windows 10 is a personal computer operating system featuring the "universal application architecture" (UAP); apps can be designed to run across multiple devices with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub and HoloLens. Windows 10 also includes a virtual desktop system, a window and desktop management feature called Task View, the Microsoft Edge web browser, support for fingerprint and face recognition login, voice-based search (Cortana), new security features for enterprise environments, and DirectX 12 and WDDM 2.0 to improve the operating system's graphics capabilities for games.

Windows 10

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

Programming includes both the specifics of the language you’re using, like Visual Basic, .NET, Java and others, but also the best practices in user experience and interfaces and the management of projects, version control and development. Other programming topics are related to web and cloud development and system and hardware programming.

Programming

A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor). These auxiliary devices are intended to be connected to the computer and used in conjunction with it. Examples of external peripherals include mouse, keyboard, printer, monitor, external Zip drive or scanner, while internal peripherals include CD-ROM drive, CD-R drive or internal modem. Today's new devices, such as tablets, smartphones and wearable computing devices are considered peripherals as they can be connected and used on a computer system. The difference, however, is that these devices can run independently of the computer system.
