NetworkManager logs
Update: running usb_modeswitch -R -v 19d2 -p 0108 after a while of plugging the usb modem in and then attempting to connect works fine. Re-assigning to usb_modeswitch. The NetworkManager log shows that the connection is attempted on ttyUSB1. According to the lsusb output the only serial port with interrupt transfer mode is ttyUSB3. This port should have been used by NM. There is nothing that usb_modeswitch can do here - except resetting the device, which you did.

Or rather to the modem-manager component which tries to autodetect the right port. I don't know if that counts as a different package ... MM currently uses "tags" via udev rules to detect which port is the main port and which ports are "aux" ports. Those are derived from the windows driver. I hadn't thought about the interrupt endpoint before. It's a pain to add new ZTE devices to the udev rules, and that obviously doesn't "Just Work", so perhaps I can augment the ModemManager logic to tag interfaces with the interrupt endpoint as the "main" port when they aren't listed in the udev rules. There are some devices which provide more than one vendor-specific interface with an interrupt endpoint, presumably for proprietary "ether" protocols. These may be bound to the "option" driver automatically and pop up as (unusable) ttyUSBs. Fortunately, in all known cases (Huawei, Olivetti) the *lower* interface with an interrupt endpoint marks the correct modem port. usb_modeswitch makes udev add a symlink to the correct port for convenience. So far, the interrupt endpoint "rule" never failed. I thought I had mentioned this fact before in some bug thread, but I can't remember exactly where that might have been. For ZTE the interface # is all over the map. I've pulled the following all out of the windows INF files: http://cgit.freedesktop.org/ModemManager/ModemManager/tree/plugins/77-mm-zte-port-types.rules and as you can see the TYPE_MODEM interface # changes pretty often; some its 0, some its 1, some its 3, some its 4. But given this information if there's an easy way to determine whether there's an interrupt endpoint on the interface using sysfs/udev then I think I can make the ModemManager ZTE plugin use that as a fallback if the device isn't specifically tagged already. I *really* would like to see annother fallback in NetworkManager: Manual override of the serial port setting (probably hidden under an "Advanced" button). Right now, if port autodetection fails, there is really no other way than to point people to other connection programs, which is quite regrettable. Does this device now work with latest ModemManager update? https://admin.fedoraproject.org/updates/ModemManager-0.4.998-1.git20110706.fc14 I've been using F15 and it works. Can't test F14, but I guess it just needed the ZTE rules you mentioned in comment 8, so it should be fine. Thanks. I have been using Fedora15. It doesn't work. (In reply to comment #12) > I have been using Fedora15. It doesn't work. What doesn't work? can you post some modem-manager debug logs? Try the following: 1) unplug your device 2) get a root terminal 3) mv /usr/sbin/modem-manager / 4) killall -TERM modem-manager 5) /modem-manager --debug 6) replug your dongle, reproduce the issue 7) paste or attach that log output from modem-manager into this bug report 8) hit Ctl+C to stop modem-manager 9) mv /modem-manager /usr/sbin/modem-manager and then we can diagnose what's going on.

Here is attached file. This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
