libusb未列出USB/IP模拟设备

有一个工具允许通过TCP/IP网络共享访问USB设备。USB设备连接到运行TCP服务器的Linux PC和运行连接到Linux的VHCI驱动程序的Windows PC。 这种方法可以在没有任何硬件的情况下模拟任何USB设备。您只需要编写TCP服务器，它将处理USB请求。（像）

但它的问题是，模拟设备并不是真正正确的。当您尝试使用libusb列出已连接的USB设备时，会出现错误“未列出的祖先…”，因为模拟设备在设备树中没有父设备。 另一方面，一些工具，如显示模拟设备

只讨论了问题，没有提供真正的解决方案

那个么问题是它在USB/IP windows驱动程序中有缺陷吗？有Windows驱动程序开发经验的人能帮上忙吗？关于父设备的交易是什么？为什么它如此重要

任何提示都将不胜感激！事先非常感谢您的帮助

UDPATE：技术上的问题是libusb无法将模拟设备的父设备（USB/IP枚举器）识别为集线器。这使得模拟设备由于父项为空而被忽略。所以问题是如何修补USB/IP驱动程序，使其作为普通USB集线器被libusb可见。问题是USB/IP windows驱动程序v0.2.0.0没有在IRP上回复。它只将IRP_MN_QUERY_功能分派给模拟设备，而不分派给总线驱动程序本身。 我已经向USB/IP驱动程序添加了IRP\u MN\u QUERY\u处理功能，现在它被libusb检测为普通USB集线器设备

UPD：

在pnp.c内部方法中

 NTSTATUS Bus_FDO_PnP (
    __in PDEVICE_OBJECT       DeviceObject,
    __in PIRP                 Irp,
    __in PIO_STACK_LOCATION   IrpStack,
    __in PFDO_DEVICE_DATA     DeviceData )

我在

开关（IrpStack->MinorFunction）中添加了新的“case”：

UPD2:还有这个：

PAGED_CODE();

stack = IoGetCurrentIrpStackLocation(Irp);
deviceCapabilities = stack->Parameters.DeviceCapabilities.Capabilities;

{
    return STATUS_UNSUCCESSFUL;
}

deviceCapabilities->DeviceState[PowerSystemWorking] = PowerDeviceD0;

    deviceCapabilities->DeviceState[PowerSystemSleeping1] = PowerDeviceD1;

    deviceCapabilities->DeviceState[PowerSystemSleeping2] = PowerDeviceD3;

    deviceCapabilities->DeviceState[PowerSystemSleeping3] = PowerDeviceD3;

您愿意分享该更改的来源吗？一堆USB调试工具在USB/IP上似乎不起作用或看不见，就像在你的例子中一样，我正试图用它来模拟一个设备。谢谢！这非常有帮助。那是
总线PDO\u查询设备caps
吗？不，是从总线PnP（）调用的总线FDO\u PnP（）。或者你的意思是什么？带有
状态=\u PDO\u QueryDeviceCaps
的行。是否定义了
\u PDO\u QueryDeviceCaps
？
