!usbkd.hub2_info_from_fdo

!usbkd.hub2_info_from_fdo 命令显示 USB 集线器的相关信息。

!usbkd.hub2_info_from_fdo FDO

参数

FDO
USB 集线器的功能设备对象 (FDO) 地址。

DLL

Usbkd.dll

示例

下面是查找 USB 集线器 FDO 地址的一种方法。 首先输入 !usbkd.usb2tree。

0: kd> !usbkd.usb2tree
...
2)!ehci_info ffffe00001ca11a0 !devobj ffffe00001ca1050 PCI: VendorId 8086 DeviceId 293c RevisionId 0002 
    RootHub !hub2_info ffffe000023201a0 !devstack ffffe00002320050

在前面的输出中，集线器 FDO 的地址作为建议命令 !devstack ffffe00002320050 的参数出现。

现在，将 FDO 的地址传递给 !hub2_info_from_fdo 命令。

0: kd> !usbkd.hub2_info_from_fdo ffffe00002320050
