If udev undid the change you'd see udev logging that.
This looks at first glance unfortunately like a timing issue.

In /lib/udev/rules.d/40-usb_modeswitch.rules please replace

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1c0b", RUN+="usb_modeswitch
'%b/%k'"

with

ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1c0b", RUN+="sleep 10 ; usb_modeswitch '%b/%k'"

Yes, I confirmed that it is a timing issue. However I had to add sleep inside /lib/udev/usb_modeswitch as uded does not accept multiple commands (separated with ";") in its config file.

BTW, for older modems (also from Huawei), it worked without the sleep.

Can you please test whether the existing -w option does the job?

Which "existing -w option" are you talking about?

There is no option like this in /lib/udev/usb_modeswitch.

I had the same problem wit a E-156 usb modem.

I found out that udev looks for /lib/udev/modem-modeswitch and we have lib/udev/usb_modeswitch . So I copied it under the new name and now it works. I have to boot with the usb-stick, after I've to disconnect it, and when I plug it again it ask me for pin and root-pwd.After I can find it in the network-manager from kde.
After I enable it there and it works.

What did you do to find this out?

I plugged the usb-stick during booting. After I read the logfile.There it was written that he look for /lib/udev/modem-modeswitch.So I made a test.

It was in 11.3 or like this when I've to look for /etc/udev/rules.d/55-umts.rules
to start it running. I means it wasn't new for me to hunt this modeswitch problems.And sometimes you need luck too.

I hope it help you for fixing the rpm.

Greetings Erich

I had the same trouble with this modem on the OpenSuse 12.1. 

It looks like time trouble and after two days testing and searching on the web I found very easy fix /workaround.

Just add the one line into the config file for the modem.
echo WaitBefore=3 >>/usr/share/usb_modemswitch/12d1\:1c00

After 3 seconds the moddem will appeared in the NetworkManager - if you are using it.

Can you test it and latter add into package fix ?

It's mentioned in the manual page

       -w --release-delay NUM
                 After issuing all bulk messages, wait  for  NUM  milliseconds
                 before  releasing the interface.  Required for some modems on
                 older systems (especially after an EJECT message)

but *not* in "usb_modeswitch --help" output. Also it's missing in the header
of the manual page. So there is another bug.

So the idea whould be to use

  usb_modeswitch -w 10000 '%b/%k

in the udev rule.

Seems you have two udev rules for the same device on your system. And the wrong/ outdated one wins. Is /etc/ude/rules.d/55-umts.rules still part of a package?
Which one?

Possible, but there is no

  usb_modeswitch.d/12d1:1c00

file available for patching, but we can use usb_modeswitch"s "-w" option here. I guess WaitBefore is specified in seconds. Then this would be 3000 ms.

Gerhard, could take care of these two changes, i.e. another udev rule for 12d1:1c00 device and the change in usb_modeswitch.d/1c0b? Thanks.
