I am trying to use IOKIT library in an executable in my project. When the executable is signed, IOServiceOpen method returns error code : e00002c2 ((iokit/common) invalid argument).

But if the code signing is removed then it works fine. Could you please let me know if I am missing some entitlements to make this work.

        Well that’s weird. I’ve no idea what’s going here. My recommendation is that you open a DTS tech support incident so that I, or one of my colleagues, can take an in-depth look.
