modemswitching should not be needed at all when the CD feature is disabled.

Does the modem work when you start the pppd connection manually?

I have issues with an K3565-Z on F12, not found the time to file a proper
bugreport yet but basically kernel recognioses it and NetworkManager for
some reason does not show the modem at all. Modemswitching is not needed
in my case because I have disabled the CD feature.
