I've removed the reference to the duplicate bug as it doesn't exist anymore.
The issue is affecting my system as well. I have an HP hs2300 HSDPA Broadband Wireless Module (Sierra MC8775). Since 13.04 the modem-manager cannot start anymore. NetworkManager is 0.9.8.0 whilst modemmanager is 0.6.0.0 This is an extract from the syslog (basically the modem-manager starts and dies in an infinite loop): Aug 4 11:45:28 TSLAsus dbus[1172]: [system] Activating service name='org.freedesktop.ModemManager' (using servicehelper) Aug 4 11:45:28 TSLAsus modem-manager[2582]: <info> ModemManager (version 0.6.0.0) starting...
