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 |
