Description Khalid Moharrum 2016-07-10 01:53:24 UTC

Description of problem:
When I plugin my Huawei E177, it does not appear in the NetworkManager applet.
I tried to start and enable ModemManager.service with no luck. In the Disks utility, I two Huawei devices appear, one as a Huawei SD Storage Drice and the other as a Huawei Mass Storage CD Drive with no options to umount any of them, when trying to umount them via the terminal I get a device not mounted message. it seems my modem is being recognized as a CD-ROM, dmesg outputs the following:

[ 82.002571] usb 2-1.1: new high-speed USB device number 4 using ehci-pci [ 82.089835] usb 2-1.1: New USB device found, idVendor=12d1, idProduct=1446 [ 82.089841] usb 2-1.1: New USB device strings: Mfr=3, Product=2, SerialNumber=0 [

Version-Release number of selected component (if applicable):
Fedora 24, ModemManager-1.6-0.3.rc3, NetworkManager-1.2.2-2, usb_modeswitch-2.3.0-1.

How reproducible:
All I did was that I upgraded my F23 to F24 using dnf.

Steps to Reproduce:
1. Install F23.
2. Run in terminal: dnf system-upgrade download --releasever=24 --allowerasing -y --nogpgcheck
3. dnf system-upgrade reboot
4. Plugin modem

Just tried again on a fresh installation of F24 and got the same results.

Comment 2 alexhorov 2016-07-18 17:41:58 UTC

Hi. I have a similar problem. My bags ID 1354574. I solved the problem adding in file /usr/lib/udev/rules.d/40-usb_modeswitch.rules lines: 
#Huawei E173 add heands
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="12d1", ATTR{idProduct}=="1446", RUN+="usb_modeswitch '%b/%k"
the modem was detected as modem
to test the modem with the command in the terminal: usb_modeswitch -v 12d1 -p 1446 -J

Thanks @alexhorov, your solution works perfectly.

Comment 4 rePeter 2016-07-21 12:27:47 UTC

Thanks for solution, I have Huawei E353/E3131 (E3272)
In Fedora 23 in /usr/lib/udev/rules.d/40-usb_modeswitch.rules  worked  generic rule:
ATTRS{idVendor}=="12d1", ATTRS{manufacturer}!="Android", ATTR{bInterfaceNumber}=="00", ATTR{bInterfaceClass}=="08", RUN+="usb_modeswitch '%b/%k'"

but it's not working in F24 and i must replace this line onto:
ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="12d1", ATTR{idProduct}=="1f01", RUN+="usb_modeswitch '%b/%k"

Comment 5 samoht0 2016-07-29 11:18:31 UTC

Looks like the generic Huawei udev rule is working again with this update (works fine now on E3372):
