Hi, I am writing a driver for a composite device with two interfaces.One interface is a modem interface and the other is a diagnostic interface to be used by diagnostic applications for the modem.My queries are as follows1.Do i need to write two separate driver modules for the two interfaces or a single driver would do the work ?
2.How does the user applications talk to the modem driver module?3.Do i need to write a driver module which enumerates the two interfaces??
Any help in this regard is highly appreciated.
Thanks in advace..
