Exactly. The currently existing apps have their USBKit.a linked in statically.
This communicates with usb_raw (using ioctls) and that's where our usb_raw
driver is compatible as it implements the same ioctls and data structure. I
don't know if the symbols would collide at all, but even if they would it
doesn't matter as the new classes are all called BUSB* whereas the old
versions were just USB*. So the symbols are different anyway.
