多配置 USB 设备 - Catalina 中的问题
Multiconfiguration USB Device - Problems in Catalina
具有第二个配置的 USB 设备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。我得到以下正在加载的接口日志，并在这些消息后立即收到终止消息。有什么问题？

我还不完全明白你现在想做什么（你提供的硬信息很少），所以我最好需要更多信息才能确定 - kext info.plist 、触发错误的 API 个调用等
但是，考虑到您在评论中列出 "IOProviderClass(IOUSBInterface)" 并且 com.apple.iokit.IOUSBFamily 出现在您引用的回溯中，我怀疑您 运行 IOUSBFamily 您似乎在 kext 中使用了旧版兼容层。我在 Mojave 中发现了这一层的各种问题，在 Catalina 中更是如此，其中一些问题与硬件有关（例如，一些问题只发生在某些 Mac 型号上）。
您可以尝试向 Apple 报告错误，但我怀疑您会得到与我将要给您的相同的建议：您应该将您的驱动程序移植到较新的 IOUSBHostFamily API。如果可能，使用 DriverKit 或作为普通用户 space 守护进程，否则作为内核扩展。如果它必须是内核扩展，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。
具有第二个配置的 USB 设备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。我得到以下正在加载的接口日志，并在这些消息后立即收到终止消息。有什么问题？

我还不完全明白你现在想做什么（你提供的硬信息很少），所以我最好需要更多信息才能确定 - kext info.plist 、触发错误的 API 个调用等
但是，考虑到您在评论中列出 "IOProviderClass(IOUSBInterface)" 并且 com.apple.iokit.IOUSBFamily 出现在您引用的回溯中，我怀疑您 运行 IOUSBFamily 您似乎在 kext 中使用了旧版兼容层。我在 Mojave 中发现了这一层的各种问题，在 Catalina 中更是如此，其中一些问题与硬件有关（例如，一些问题只发生在某些 Mac 型号上）。
您可以尝试向 Apple 报告错误，但我怀疑您会得到与我将要给您的相同的建议：您应该将您的驱动程序移植到较新的 IOUSBHostFamily API。如果可能，使用 DriverKit 或作为普通用户 space 守护进程，否则作为内核扩展。如果它必须是内核扩展，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。
