!usbkd._ehcidd
!usbkd._ehcidd 命令會顯示來自usbehci!_DEVICE_DATA 結構的資訊。
!usbkd._ehcidd StructAddr
參數
結構Addr
usbehci!_DEVICE_DATA 結構的位址。 若要尋找 usbehci!_DEVICE_DATA 結構的位址,請使用 !usbhcdext 或 !usbhcdlist。
DLL
Usbkd.dll
範例
以下是取得 usbehci!_DEVICE_DATA 結構的位址的一種方式。 首先輸入 !usbkd.usbhcdlist。
0: kd> !usbkd.usbhcdlist

在上述輸出中,ffffe0000781bda0
是 _DEVICE_DATA 結構的位址。
現在將結構地址傳遞至 !_ehcidd
