Hi All,

I am writing USB bulk device driver for Mac OS X 10.3 and above, using IOKitFramework and Corefoundation , and have following query:

My usb device saves some data in volatile cells. So as soon as the system suspends, the power supply goes off and the data gets lost.

I need to save the same info before the system suspends, So Is there any notification event available for the same?

For example, I am registering an interest notification of this device being removed by using "IOServiceAddInterestNotification" I hope there must be some similar kind of notification events to notify the USB device while its going to suspend mode.

All comments suggestions are welcome

Thanks and Regards,
