Actually,

"usbifif" is for attaching USB Interfaces, of which a device can have
multiple instances and/or varieties.  "usbdevif" is for attaching the entire
USB device.  Typically USB standard Classes use USB Interfaces.

Whether the USB device or USB Interface has network interface functionality
is unrelated to the above terms.
