!usb3kd.hub_info

  • 项目

!usb3kd.device_info 命令显示有关 USB 3.0 树中中心的信息。

!usb3kd.hub_info DeviceExtension

参数

DeviceExtension
中心功能设备对象 (FDO) 的设备扩展地址。

DLL

Usb3kd.dll

示例

若要获取设备扩展的地址，请查看 !usb_tree 命令的输出。 在以下示例中，根中心的设备扩展地址为 0xfffffa8005ad92d0。

3: kd> !usb_tree

## Dumping HUB Tree - !drvObj 0xfffffa800597f770
--------------------------------------------
Topology
--------
1)  !xhci_info 0xfffffa80051d1940  ... - PCI: VendorId 0x1033 ...
    !hub_info 0xfffffa8005ad92d0 (ROOT)
        !port_info 0xfffffa8005a5ca80 !device_info 0xfffffa8005b410c0 Desc: <none> Speed: High
        ...

现在可以将设备扩展的地址传递给 !hub_info 命令。
