I have a bit more investigated the bug and found the following: 1. run udevadm control --log-priority=debug 2. plug the phone (A1200) to usb 3. look at syslog
Part of my syslog: May 4 12:52:40 lena-laptop udevd-event[7116]: LINK 'serial/by-id/usb-Motorola_Motorola_USB_Modem-if00' /lib/udev/rules.d/60-persistent-serial.rules:17 May 4 12:52:40 lena-laptop udevd-event[7116]: mknod(/dev/.tmp-char-166:0, 020600, (166,0)) May 4 12:52:40 lena-laptop udevd-event[7116]: chmod(/dev/.tmp-char-166:0, 020600) May 4 12:52:40 lena-laptop udevd-event[7116]: chown(/dev/.tmp-char-166:0, 0, 0) May 4 12:52:40 lena-laptop udevd-event[7116]: IMPORT 'nm-modem-probe --vid 0x22b8 --pid 0x3802 --usb-interface 00 --driver cdc_acm --delay 3000 --export /dev/.tmp-char-166:0' /lib/udev/rules.d/77-nm-probe-modem-capabilities.rules:20 May 4 12:52:40 lena-laptop udevd-event[7116]: 'nm-modem-probe --vid 0x22b8 --pid 0x3802 --usb-interface 00 --driver cdc_acm --delay 3000 --export /dev/.tmp-char-166:0' May 4 12:52:40 lena-laptop udevd-event[7116]: '/lib/udev/nm-modem-probe' (stderr) 'error writing command: 5' -------------------------------------------------------------------------------------------------------------------------^^^^^^^^^^^^^^^^^^^^^^^^^^^^ May 4 12:52:46 lena-laptop last message repeated 19 times May 4 12:52:46 lena-laptop udevd-event[7116]: '/lib/udev/nm-modem-probe' (stdout) 'ID_NM_MODEM_PROBED=1' IMHO the problem is here: '/lib/udev/nm-modem-probe' (stderr) 'error writing command: 5' -- NetworkManager does not detect Motorola A1200 phone https://bugs.launchpad.net/bugs/368723 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
