After adding previous property there is:
0024:trace:wbemprox:wbem_services_ExecQuery 041923E0, L"WQL", L"Select * From Win32_PnPEntity where ClassGuid = '{4d36e967-e325-11ce-bfc1-08002be10318}'", 0x10, 00000000, 0012F1D8
That's the DiskDrive class GUID, so it's looking for a disk drive. It can be retrieved with SetupDiGetDeviceProperty(DEVPKEY_Device_ClassGuid) but we don't create registry entries for disk drives yet. I think mountmgr would be the right place to do that.
