Necflash on Mac OS X wit Optiarc AD-7170A: drive not supported



just got here from
I wanted to update my firmware but necflash -scan reports this message:
List of supported devices:
No supported devices found

I know, i could try to put the drive into a PC and try to update there.
But at the moment this is no option.
Can anbody give me some advice how to install the firmware on my Mac?
