Hi,
I am using LPC controllers and trying to talk to modem(AT commands) using USB drivers.
I have enumerated my USB modem from LPC controller and read USB device’s configuration parameters(interface,endpoint etc) from LPC.
There is two interfaces with each has two end points.Both interface’s class type is Mass storage.How to find or identify modem interface number???so that i can send AT command to that interface(talk to modem).
But some modems has only one interface(for both Mass storage and Modem).In that how can lpc identify modem and talk to modem.If i missed anything,pls let me know??Pls share your experience on this.
Thanks
