Hi,

I've problems establishing an umts connection with a Sony Ericsson F3307.


P:  Vendor=0bdb ProdID=190a Rev= 0.00
S:  Manufacturer=F3307
S:  Product=F3307

modem-manager tries to communicate via the serial tty node of the device, 
which causes following error.

May 17 11:13:37 ThinClient modem-manager[2331]: <info>  (ttyACM0) opening 
serial port... 
May 17 11:13:37 ThinClient modem-manager[2331]: <info>  Modem 
/org/freedesktop/ModemManager/Modems/0: state changed (disabled -> enabling) 
May 17 11:13:38 ThinClient modem-manager[2331]: Invalid error code: 272
May 17 11:13:38 ThinClient modem-manager[2331]: <info>  Modem 
/org/freedesktop/ModemManager/Modems/0: state changed (enabling -> disabled) 
May 17 11:13:38 ThinClient modem-manager[2331]: <info>  (ttyACM0) closing 
serial port... 
May 17 11:13:38 ThinClient modem-manager[2331]: <info>  (ttyACM0) serial port 
closed 

If i load the usb-wwan module, the modem-manager tries to send a dhcp request 
to a network-interface ttyACM0 which doesn't exist. The usb-wwan module brings 
up a wwan0 interface.

I have no further logs for the dhcp issue at the moment.

best regards
Harald Jung
