int usb_interface_claimed (struct usb_interface * iface);
This should be used by drivers to check other interfaces to see if they are available or not. If another driver has claimed the interface, they may not claim it. Otherwise it's OK to claim it using usb_driver_claim_interface.
Returns true (nonzero) iff the interface is claimed, else false (zero).
