啊哈！
一点背景...我不是.Net 程序员。我过去对一些 C 源代码进行了 gcc 编译，但不是通过贸易。我的许多业余爱好者都在 Linux 上工作。我有一个需要在 Linux 中访问的 USB 设备，但源代码位于 .NET 中（FlashcatUSB 软件位于 @ https://www.embeddedcomputers.net/software/）。
我已按照以下说明从此处在 Linux 上安装 .NET： https ://docs.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#2004-
我可以构建软件并尝试运行软件，但访问 USB 设备超时。这些是采取的步骤：
