This depends a little bit on how your modem is being recognized.  If it
is recognized as a storage device, then yes, usb_modeswitch will
probably be required.

If it is already recognized as a modem and the rules are not present in
ofono.rules, then you will need to perform the steps I mentioned in my
previous mail.
