Yes, USB can have a different class for each interface, with multiple interfaces within a given configuration - so you can have an device with multiple configurations, one configuration offering USB storage, one offering USB networking, one offering USB serial, and one offering all of the above, each on different endpoints. However, I don't know how well certain program launchers masquerading as operating systems would handle such devices, and I think that's why most devices restrict themselves to only one interface per configuration.
