WinUSB获取USB设备端点信息

使用WinUsb_QueryInterfaceSettings函数获取指定接口下的所有信息，然后解析端点信息并打印。

struct PIPE_ID
{
    UCHAR  PipeInId;
    UCHAR  PipeOutId;
};

BOOL QueryDeviceEndpoints (WINUSB_INTERFACE_HANDLE hDeviceHandle, PIPE_ID* pipeid)
{
    if (hDeviceHandle==INVALID_HANDLE_VALUE)
    {
        return FALSE;
    }

    BOOL bResult = TRUE;

    USB_INTERFACE_DESCRIPTOR InterfaceDescriptor;
    ZeroMemory(&InterfaceDescriptor, sizeof(USB_INTERFACE_DESCRIPTOR));

    WINUSB_PIPE_INFORMATION  Pipe;
    ZeroMemory(&Pipe, sizeof(WINUSB_PIPE_INFORMATION));


    bResult = WinUsb_QueryInterfaceSettings(hDeviceHandle, 0, &InterfaceDescriptor);

    if (bResult)
    {
        for (int index = 0; index < InterfaceDescriptor.bNumEndpoints; index++)
        {
            bResult = WinUsb_QueryPipe(hDeviceHandle, 0, index, &Pipe);

            if (bResult)
            {
                if (Pipe.PipeType == UsbdPipeTypeControl)
                {
                    printf("Endpoint index: %d Pipe type: Control Pipe ID: %d.\n", index, Pipe.PipeType, Pipe.PipeId);
                }
                if (Pipe.PipeType == UsbdPipeTypeIsochronous)
                {
                    printf("Endpoint index: %d Pipe type: Isochronous Pipe ID: %d.\n", index, Pipe.PipeType, Pipe.PipeId);
                }
                if (Pipe.PipeType == UsbdPipeTypeBulk)
                {
                    if (USB_ENDPOINT_DIRECTION_IN(Pipe.PipeId))
                    {
                        printf("Endpoint index: %d Pipe type: Bulk Pipe ID: %c.\n", index, Pipe.PipeType, Pipe.PipeId);
                        pipeid->PipeInId = Pipe.PipeId;
                    }
                    if (USB_ENDPOINT_DIRECTION_OUT(Pipe.PipeId))
                    {
                        printf("Endpoint index: %d Pipe type: Bulk Pipe ID: %c.\n", index, Pipe.PipeType, Pipe.PipeId);
                        pipeid->PipeOutId = Pipe.PipeId;
                    }

                }
                if (Pipe.PipeType == UsbdPipeTypeInterrupt)
                {
                    printf("Endpoint index: %d Pipe type: Interrupt Pipe ID: %d.\n", index, Pipe.PipeType, Pipe.PipeId);
                }
            }
            else
            {
                continue;
            }
        }
    }

done:
    return bResult;
}
