매개 변수

FDO
USB 허브에 대한 기능적 디바이스 개체(FDO)의 주소입니다.

DLL

Usbkd.dll

예제

USB 허브의 FDO 주소를 찾는 한 가지 방법은 다음과 같습니다. 먼저 !usbkd.usb2tree를 입력 합니다.

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

이전 출력에서 허브에 대한 FDO의 주소는 제안된 명령 !devstack ffffe00002320050의 인수로 나타납니다.

이제 FDO 의 주소를 !hub2_info_from_fdo 명령에 전달합니다.
