I am developing a user mode driver for a smart card reader, for which i am using pcsc daemon which loads a driver(a linux_driver.so file) from a predetermined path stored in the file system.

The problem is that, during system suspend and resume is there any means to register a handle with the power manager from my user mode driver and gain control of the power manager ?

I am trying to use acpi daemon... not sure whether it will work.

with regards
