huawei usb modem not detected by opensuse 11.4

Hi siouxzy
your problem reminds of the difficulties I had after upgrading to 12.2.

Many clever advices didn’t work, but I got the impression that it had to
do with the device being locked. Greyed menu-items for example.

So I simply deactivated PIN-entry (upon plugging the device).
No further workaround needed.

Hope this works for you too.

FYI - Full description of my symptoms in german can be found here:

Thanks for your suggestion Henning, pin is disabled so don’t think the device is locked, sorry can’t read German :confused:

Hi Henning, thanks again for your help, finally got around to translating your link and yes looks like similar problems with mobile broadband in 12.2 as well… hmmm what to do !? the words of cafe4926 come to mind again
“These devices are many and varied and require some work to get them going (no guarantee). I had one once and it went in the trash, yes it was that good.”
Wired or wireless are not options i have and my understanding and knowledge of linux is not great but guess i’ll keep plugging away at trying to get the mobile to work :dont-know:

You storage device was assigned as /dev/sr1, so the following should do the trick

eject /dev/sr1

then check it /dev/ttyUSB* exists

ls -l /dev/ttyUSB*

For reference, my built-in 3G modem device has the following nodes assigned

crw-rw---- 1 root dialout 188, 0 Oct 17 06:47 /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 1 Oct 17 06:47 /dev/ttyUSB1
crw-rw---- 1 root dialout 188, 2 Oct 17 06:47 /dev/ttyUSB2
24 
# eject /dev/sr1
# ls -l /dev/ttyUSB*
 ls: cannot access /dev/ttyUSB*: No such file or directory

guess this means it doesn’t!?

Okay, my bad. I think your E353 device is one of the new generation devices that appear as a network device when activated, although I’m not sure if this device is supported by such an old kernel. It may be that you need to upgrade to openSUSE 12.2 first.

26

OK thanks i’ll do that and see what happens.

27

The key to it will be observing a new network interface show up when you plug it in.

/sbin/ifconfig -a

IIRC, the ‘cdc_ether’ module supports these type of USB-type network devices. If the interface shows up, then you should be good to go with respect to configuring via the network manager (as a wired ethernet device). If it doesn’t, it may not yet be supported…

I had forgot about this thread that I assisted with:

Same chipset as your device

idVendor=12d1, idProduct=1f01

Once you have 12.2 installed, try configuring as per the discussion.

Eureka! you’re right Deano needed 12.2, thanks, automatic configuration after install with the dongle plugged in and suse configured it as a wired ethernet device all i had to do was switch to controlled by network manager in Yast, start network manager by adding the widget (seemed to be the only way to get to it in 12.2 as wasn’t listed as applet) and connection was made :slight_smile: am so happy and only wish i hadn’t been put off of going for 12.2 sooner, it seemed there were a lot of folks having problems with it and so i lost faith :slight_smile: looking forward to downloading all the good stuff suse has to offer and loving my new OS, thanks again to all.

Fantastic! Happy that it is solved!
