** Description changed: + Ubuntu 11.10 Oneiric uname -a: Linux home 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:50:42 UTC 2011 i686 i686 i386 GNU/Linux network-manager: 0.9.1.90-0ubuntu3 modemmanager: 0.5-1ubuntu1 -------------------------- If I connect to a 3G network, keep the connection open (stay connected), and either restart a computer or stop-start network-manager, the modem (Huawei E173) will not be "detected" anymore (cannot open port). Worked fine in Natty. Ways to fix: unplug the modem AND stop-start network-manager (which stops-starts modemmanager), plug modem back in. Seems like the modem "keeps connection open" while still being powered on and cannot be initialized properly. Very irritating since it cannot be fixed without modem unplugging. Full debug info below. Details in short (see attached files for full debug info): Modem after connecting to 3G network, then either restarting the computer or restarting network-manager (syslog): Oct 15 08:54:08 home kernel: [ 9.435382] USB Serial support registered for GSM modem (1-port) Oct 15 08:54:08 home kernel: [ 9.436317] option 1-6:1.0: GSM modem (1-port) converter detected Oct 15 08:54:08 home kernel: [ 9.436478] usb 1-6: GSM modem (1-port) converter now attached to ttyUSB0 Oct 15 08:54:08 home kernel: [ 9.436522] option 1-6:1.3: GSM modem (1-port) converter detected Oct 15 08:54:08 home kernel: [ 9.436611] usb 1-6: GSM modem (1-port) converter now attached to ttyUSB1 Oct 15 08:54:08 home kernel: [ 9.436622] option 1-6:1.4: GSM modem (1-port) converter detected Oct 15 08:54:08 home kernel: [ 9.436703] usb 1-6: GSM modem (1-port) converter now attached to ttyUSB2 Oct 15 08:54:08 home kernel: [ 9.436766] option: v0.7.2:USB Driver for GSM modems Oct 15 08:54:08 home modem-manager[877]: <info> ModemManager (version 0.5) starting...

Then sends five AT^GETPORTMODE commands to ttyUSB0, receives no reply. Then sends three AT+GCAP commands to ttyUSB0, receives no reply. Closes port ttyUSB0. Reopens port ttyUSB0. Sends two 00 78 f0 7e signals to ttyUSB0, receives no reply. Closes port ttyUSB0. At the same time, ttyUSB1 and ttyUSB2 continuosly get "re-checking support..." and "deferring support check" without success (and keep getting that after ttyUSB0 gets closed). Dumb guess: Maybe a different AT command should be sent to "reset" the modem if it "thinks there is a session open"?
