We discuss this IOCTL issue with Alan C. and David W. and I didn't see any 
other solution for this.
if someone has a good solution for that we are happy to hear it.

the reason that we use IOCTL is that we need to "associate" (Connect) the 
current file description to a FW Client/Feature.
(opening a comm channel) .
and in addition there is a security issue that we would like limit the access 
to mei driver to system admins.

If there other methods for achieving this ?

Thanks
