USB HID Compliant Device issues with Windows 10
Can't communicate with the CY8CKIT-050 PSoC5 Dev Kit using USB in Windows 10 - was OK in Windows 7

We have a project on a CY8CKIT-050 which communicates with a PC via USB. The PC application is based on the AN82072 PC Host Application developed in VS.NET 2013 in C# and it has been working fine for several months on a Windows 7 PC. We have recently purchased a new Windows 10 PC an have been trying to migrate the PC application across but hit some problems.

Eseentially, the CY8CKIT-050 isn't being recognised by the Host Application. Looking in Visual Studio, the issue is encounted when the following line of code executes in the PC application: -

USBDevices = new USBDeviceList (CyConst.DEVICES_HID);

This should return a list of "HID Compliant Device" devices in "USBDevices" but actually returns NULL resulting in an overflow exception - this works correctly on the original Windows 7 PC. Interestingly, the debug message actually says "Stopped at Exception: ToInt32" which may be a clue.

Initially I thought that the problem was that the wrong driver had been selsected by the OS - it had aytomatically loaded the "HID Compliant Vendor Defined Device" driver which I then switched to the correct "HID Compliant Device" but this made no difference. I then tried a later version of the CYUSB.dll in the VS project but this too made no difference.

I have now run out of ideas so wondered if anybody had anything that might help on this.

Many thanks
