@hector: are you able to get modem-manager debug logs while trying to reproduce the issue, and post them here? just to confirm it's the same issue.
You can get the debug logs with these steps: $> sudo -s $> /etc/init.d/network-manager stop $> killall modem-manager $> modem-manager --debug And in another terminal: $> sudo /etc/init.d/network-manager start Then try to reproduce the issue; and once done attach whole /var/log/syslog file to the bugreport (should include the debug logs). And you can then Ctrl+C in the first terminal to get modem-manager restarted without debug logs automatically. ** Description changed: Upgraded to Natty yesterday and since then my Huawei E160G is no longer detected properly by ModemManager. It seems the kernel closes the USB port during ModemManager's Huawei plugin probe, so it never gets fully connected and probing loops forever (see attached syslog with - ModemManager debug logs enabled). Also, when kernel says "option: - option_instat_callback: error -108", the whole PC gets frozen for 1-2 - seconds. + ModemManager debug logs enabled). + + Also, when kernel says "option: option_instat_callback: error -108", the + whole PC gets frozen for exactly 10 seconds. This issue happens with both Natty's default ModemManager (0.4+git.20110124t203624.00b6cce-2ubuntu1) and latest git master, so it really seems something kernel-related. aleksander@ares:~$ uname -a Linux ares 2.6.38-8-generic-pae #42-Ubuntu SMP Mon Apr 11 05:17:09 UTC 2011 i686 i686 i386 GNU/Linux This issue is not reproducible neither in Maverick nor in Fedora15 (kernel 2.6.38-3-18.fc15.i686) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772577 Title: Kernel in Natty disconnects Huawei E160G, ModemManager can't use it -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
