Question

具有第二个配置的USB设备的接口的驱动程序正在获取KIOServiceTerminated。配置1中类似接口的相同驱动程序正在加载并正常工作。我收到正在加载的接口的以下日志，并在这些消息之后立即收到Terminate消息。有什么问题吗？

Answer 1

目前我还不太了解您要做什么（您提供的硬信息很少），因此理想情况下，我需要确定一些其他信息-kext info.plist，API调用触发错误等的原因。

但是，考虑到您在注释中列出了“ IOProviderClass（IOUSBInterface）”，并且在引用的回溯中显示了com.apple.iokit.IOUSBFamily，我怀疑您正在遇到维护错误的IOUSBFamily中的错误。您似乎在kext中使用的旧兼容性层。我在Mojave中发现了这一层的各种问题，在Catalina中甚至更多，其中一些问题取决于硬件（例如，某些问题仅在某些Mac型号上出现）。

您可以尝试将错误报告给Apple，但是我怀疑您会得到与我相同的建议：您应该将驱动程序移植到较新的IOUSBHostFamily API。如果可能，请使用DriverKit或用作常规用户空间守护程序，否则用作内核扩展。如果必须是内核扩展，则macOS SDK中的IOUSBHost*.h头文件在每个文件顶部的注释中包含移植说明。
