I bummed to hear you've had to revert back to 9.04. I've found that using the synaptic package manager (System --> Administration --> Synaptic Package Manager) one *can* mark the modem manager for complete removal (just search on 'modem'). Then, a reboot will eliminate the /usr/sbin/modem-manager process hogging the USB modems (like /dev/ttyACM? and/or /dev/ttyUSB?). This makes GNOME-PPP usable again ... and wvdialconf too. Try wvdialconf first (just to pull in some optimal modem configuration settings).
I've done this ... and I'm getting connected. I'm not posting the results just yet ... since I'm currently stuck at a terminal server prompt from my ISP. When I (or gnome-ppp or wvdial) tries the 'ppp' command, I'm getting a Requested Service Not Authorized. This is clearly a glitch on my ISP's end. I'll talk with them tomorrow about this. Maybe they've limited their offering to what MS Windows using (e.g. SLIP/CSLIP). Who knows? I'm still working through this weirdness. By the way, I've used 'gtkterm' to confirm precisely what is what with the 'log' (button) view of what is going on behind GNOME-PPP. Type ATZ a couple of times to synch-up/negotiate port speed (and leave stop bits, parity, etc. as they default). At any rate, I'm pretty sure I'm seeing 'real' results (as opposed to GUI muddle). I just thought you might appreciate the early partial/results. While Ubuntu 9.10 seems unusually ornery ... it doesn't look wholesale broken. Ultimately, this looks like a modem-manager bug (that I'll file if nobody else does). The modem-manager leaves breadcrumbs in /var/log/syslog about *NOT* recognizing the USB USR modem as an ADSL modem (cuz it isn't). At that point, the modem-manager really *should* let go of the device. Instead, it sits (or squats) on a device that it knows it cannot use. Blech. That is a bug.

Status in “modemmanager” package in Ubuntu: New Bug description: Binary package hint: modemmanager On Ubuntu 9.04 I had no problems using old (but reliable) dialup modem Zyxel Omni Mini. I connected it to USB port using Prolific PL2303 USB- to-Serial connector. It sat on /dev/ttyUSB0 and worked just perfectly with GnomePPP & WVDial. After upgrade to 9.10 I tried to dial my ISP and got "/dev/ttyUSB0 Device or resource is busy" (or something very similar to). With SUDO I could make wvdial to dial an ISP and establish connection, but it was not a good solution. Thorough LSOFing gave me that the device is opened by modem-manager process. Attempts to PKILL it failed: it respawned again and again. I've apt-get remove modemmanager, then pkilled it again and got non-root usable modem! But now NM does not auto-discover GSM-phones attached to /dev/ttyACM0 Guys, you did a great job, but do not forget about dialup users, please! Would devteam do something to make modemmanager not capturing USB-modem, if it is not GSM one? edit: forgot to mention a package: modemmanager_0.2.git.20091014t233208.16f3e00-0ubuntu1_i386.deb from Ubuntu 9.10 official install DVD. -- Can't use USB/PL2303-attached Zyxel Omni Mini with non-root user https://bugs.launchpad.net/bugs/482971 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
