I pushed some fixes to the 'qmi-support' branch of ModemManager trying
to cope with the 'usb'->'usbmisc' transition. Basically, I'm assuming
that either one or the other may appear, trying to avoid the need for a
runtime kernel version check. Could you test that in the newest kernels
with 'usbmisc'? It seems to work ok for the older ones with 'usb'.
