CyUSB.dll is obsolete and we recommend you to use Windows HID libraries for your application.
Your application maybe crashing because of some issues we have seen in the past of running Visual Studio and PSoC Creator simultaneously. We are working on a fix though we cannot guarantee on any timeline.
We recommend you to use one IDE at a time for now.
OK, I will check with the software developer to see if he can figure out how to use the Windows HID libraries.
We are not running Creator and the SW application at the same time so that is not our issue.
Just as a note, it looks like you're talking about the Windows HID Library as part of the UWP (Windows.Devices.HumanInterfaceDevice Namespace - UWP app developer | Microsoft Docs )?
Unfortunately UWP does not support Windows 7 or earlier, only 8 onwards.
If you're like me and still need to support legacy OS like XP/Vista/7, I've used HIDSharp which works in .NET framework versions as early as .NET 2.0
Thank you very much for the tip!!!
