        The drivers for the interfaces of   USB device with 2nd configuration are getting KIOServiceTerminated . The same drivers for similar interfaces in configuration 1 are loading and working properly. I get the following log for the interface that is geting loaded and immediately getting Terminate message after these messages. What is the problem?
