IoGetDeviceObjectPointer return STATUS_INVALID_DEVICE_REQUEST in Vista

Hi all,
I got STATUS_INVALID_DEVICE_REQUEST (0xC0000010) returned from IoGetDeviceObjectPointer in Vista, but working fine in Win7 and XP, the ObjectName is something like “??\USB#vid…” or “\Device\USBPDO-10”, any idea?

Can you please check with Winobj if this path shows up there in Vista?

Please retrieve the name using IoGetDeviceInterfaces, do not hardcode it.

Thanks guys, I got it fixed by using enumerating the device directory.

Incorrect for PnP devices, use IoGetDeviceInterfaces.
