It seems that USB should have this capability already; the device
interfaces are attached individually unless a driver claims for the whole
device. So far as I know, all the USB interfaces would be attached
separately if they presented themselves properly.
As to why your card doesn't show up that way I couldn't say, but if it is
presenting itself in a manner not understood by our stack then either our
stack could be fixed or a special driver written to handle the device and
split the functionality into appropriate directions..
