Windows Server 2019 Docker FT_Open -> FT_DEVICE_NOT_OPENED RRS feed

  • Question

  • I use the "ftd2xx64.dll" to implement a light control using "Enttec Open DMX USB" with C# and DotNet 3.0. On Windows Server 2019 the program is working. As soon as I start it in Docker (mcr.microsoft.com/dotnet/core/aspnet:3.0-nanoserver-1809) I get the status "FT_DEVICE_NOT_OPENED" when calling "FT_Open".

    In Ubuntu, I was able to fix this problem by putting "ftdi_sio" and "usbserial" on the blacklist.

    Unfortunately, I find no helpful hints for Docker with a Windows Server 2019 host. I think it may have something to do with the fact that possibly the driver on the host computer already occupies the device. Therefore, you can no longer use the device from the Docker.

    Are there any possible solutions? I would be very grateful if you could show me a possible solution, or at least give me some idea.
