Thanks Thomas for the work around I have made the subsystem2 as Virtual
Mode, but still the error persists.
Error I am getting is related to the subsystem1.

Modified conf.in

# Direct controller

Can you please tell me more about "domain:bus:func:dev", from where I can
extract this data ?

Thanks and Regards
