I have the same problem with this usb modem. The stick used to work fine from Lucid to Maverick, but stopped working in Oneiric. Although I got the modem to work eventually using smiki's workaround (comgt and restart of network manager), this is a really inconvenient solution. Frankly, I don't understand why this is happening in the first place.
I have attached my dmesg output after connecting the stick. The small led lights up and, according to lsusb, is attached in modem mode: Bus 001 Device 005: ID 19d2:0031 ONDA Communication S.p.A. ZTE MF110/MF636 It is not recognised as a network device, however, and network manager does not offer an option to connect to a mobile broadband network. Please let me know if I can supply further information. I'd love to see this fixed. ** Attachment added: "output of dmesg after attaching modem" https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch-data/+bug/891307/+attachment/2759378/+files/dmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/891307 Title: usb_modeswitch does not recognize ZTE 19d2:0031 modem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-modeswitch-data/+bug/891307/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
