Why SMART-Driver does not be registered

[kingeaglewang]

Hi,

After installing the driver and mount the device, the SMART driver is shown in the command ioreg
But I am curious why the state of SMART driver is not registered.

| | | | | +-o fi_dungeon_driver_IOSATDriver <class fi_dungeon_driver_IOSATDriver, id 0x100001119, !registered, !matched, active, busy 0 (264 ms), retain 8>

I search for this issue.
It says we have to call registerService() method, and then the driver would be registered.
I find that you have called the method in the CreateStorageServiceNub function
nub->registerService ( );
And the kernel log show the driver execute this function without fail.
Is there anything wrong?
I don't know why the SMART driver is not registered.

Thanks

P.S. The kernel log is like the following
