    "Attempted to read or write protected memory" on new USBDeviceList call

    Sebe_1916866

      Although I'm running .NET C#, I had this issue initially when trying to run in x64: CyUSB.dll - x64 - Matlab problem

      Any CPU would work.

       

      Anyway, I followed the advice to try CyUSB 1.2.3.0 and now I'm getting "Attempted to read or write protected memory"... no matter what configuration I build with.

       

      NameValueType
      StackTrace" at CyUSB.PInvoke.HidD_FreePreparsedData(Byte* data)\r\n at CyUSB.CyHidDevice.Open(Byte dev)\r\n at CyUSB.USBDeviceList..ctor(Byte DeviceMask, App_PnP_Callback fnCallBack)\r\n at CyUSB.USBDeviceList..ctor(Byte DeviceMask)\r\n at USBBootloaderHost.Form1..ctor() in C:\\CyBootloaderHost\\USBBootloaderHost\\Form1.cs:line 57\r\n at USBBootloaderHost.Program.Main() in C:\\CyBootloaderHost\\USBBootloaderHost\\Program.cs:line 18"string

       

      Any advice appreciated.

      My final goal is to add a feature to my app to program PSoC over USB.

      Are there any examples I can download?

      Thanks!
