No, we're working on something more lightweight (See

Userland would be satisfied if we had a sysfs node with a description of the
current scenario, e.g.
"charger" (our 1A charger is connected)
"gadget" (we are connected to a host that enumerated us)
"host" (we are connected to a gadget)
the device daemon can then load the proper module based on either user
interaction or context (profile or preference).
