Problem with Huawei E220 after latest kernek upgrade

English Hardware
#1

Hi to all,

I am using the opensuse 10.3. Last time I did an online upgrade, the kernel was upgrade to the last version 2.6.22.18 and after reboot my Huawei E220 USB modem didn’t work.

I had to downgrade to the previous version 2.6.22.17 to be able to connect to the internet.

The errors I got were:

Does someone knows what happened?

Take a look at:
Huawei E220 & recent kernels… anyone else experiencing some issues? - Broadband & ADSL Forums - Internet, Gaming, Hardware, Software
which claims a fix that worked for 2 people.

It’s probably some subtle change made to the driver (or USB-support code!?)
or whatever, which needs this other change, which didn’t get included in the
kernel update. Of course, I’m just guessing.

Hope this helps…

hi, my Novatel mc950d Ovation modem also doesn’t work with Suse > 11.1.
It worked after the installation until i did the first update.
Since then the modem gets resetted.
I also tried Suse 11.2 where the modem hangs up (pppd error 16).
Under 10.3 it all worked fine. Changes to the USB System?
