Hi, The latest version of usb_modeswitch (1.2.0-1.fc15) breaks the ability to use the Mecer WM81 3G modem. Downgrading to the previous version (1.1.7-1.fc15) solves the problem. The modem uses the Vendor Id 0x1c9e and Product Id 0x9605, found in the /etc/usb_modeswitch.d/0x1c9e:f000 file. With the newest version of usb_modeswitch, the device is recognised, but it does not create any of the ttyUSB* devices for the modem to attach to. The /var/log/messages log file reports the following with version 1.20.-1.fc15: Nov 17 21:38:36 itnotebook kernel: [ 1480.336713] usb 2-1.2: new high speed USB device number 4 using ehci_hcd Nov 17 21:38:36 itnotebook kernel: [ 1480.424456] usb 2-1.2: New USB device found, idVendor=1c9e, idProduct=f000 Nov 17 21:38:36 itnotebook kernel: [ 1480.424462] usb 2-1.2: New USB device strings: Mfr=3, Product=2, SerialNumber=4 Nov 17 21:38:36 itnotebook kernel: [ 1480.424467] usb 2-1.2: Product: USB Modem Nov 17 21:38:36 itnotebook kernel: [ 1480.424470] usb 2-1.2: Manufacturer: USB Modem Nov 17 21:38:36 itnotebook kernel: [ 1480.424474] usb 2-1.2: SerialNumber: 1234567890ABCDEF Nov 17 21:38:36 itnotebook mtp-probe: checking bus 2, device 4: "/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2" Nov 17 21:38:36 itnotebook mtp-probe: bus: 2, device: 4 was not an MTP device Nov 17 21:38:38 itnotebook logger: usb_modeswitch: using overriding config file /etc/usb_modeswitch.d/1c9e:f000; make sure this is intended Nov 17 21:38:38 itnotebook logger: usb_modeswitch: please report any new or corrected settings; otherwise, check for outdated files Nov 17 21:38:40 itnotebook usb_modeswitch: switching 1c9e:f000 (USB Modem: USB Modem) Nov 17 21:38:42 itnotebook kernel: [ 1486.038308] usb 2-1.2: USB disconnect, device number 4 Nov 17 21:38:42 itnotebook kernel: [ 1486.214789] usb 2-1.2: new high speed USB device number 5 using ehci_hcd Nov 17 21:38:42 itnotebook kernel: [ 1486.302732] usb 2-1.2: New USB device found, idVendor=1c9e, idProduct=9605 Nov 17 21:38:42 itnotebook kernel: [ 1486.302737] usb 2-1.2: New USB device strings: Mfr=3, Product=2, SerialNumber=4 Nov 17 21:38:42 itnotebook kernel: [ 1486.302741] usb 2-1.2: Product: USB Modem Nov 17 21:38:42 itnotebook kernel: [ 1486.302744] usb 2-1.2: Manufacturer: USB Modem Nov 17 21:38:42 itnotebook kernel: [ 1486.302746] usb 2-1.2: SerialNumber: 1234567890ABCDEF Nov 17 21:38:43 itnotebook usb_modeswitch: switched to 1c9e:9605 (USB Modem: USB Modem) Nov 17 21:38:43 itnotebook kernel: [ 1487.721593] usbcore: registered new interface driver uas Nov 17 21:38:43 itnotebook kernel: [ 1487.731351] Initializing USB Mass Storage driver...

Yes, I have same problem with Huawei Joy (Vodafone 845) with version 1.2.0-1.fc15 from latest updates. Downgrade to 1.1.7-1.fc15 works for me.
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. 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 '15' 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 15 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
