Access Point Huawei E5220 plugged by USB does not work in Kubuntu 14.04

After installing the latest version Kubuntu 14.04 my 3G + WiFi Access Point Huawei E5220 has stopped working correctly. The Access Point is not available from the system if connected by USB cable. Access to the device by browser at 192.168.1.1 address is not possible, 'ping' does not pass (host unreachable). Interface wwan0 is up and properly configured. The output of 'dmesg' and 'lsmod' commands is similar as in 12.04 (where the Access Point is working well!), nothing unusual except the string (dmesg):

systemd-udevd[2936]: Failed to apply ACL on /dev/sr1: No such file or directory

The problem is solved at once by rolling back to the kernel 3.8.0 from the 12.04 kernel-repository. It also does not present the error string that I have indicated above (dmesg). I can recommend this as a temporary solution. Add the repository:

deb http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu precise main

And install the latest available kernels 3.8.0:

sudo apt-get update

sudo apt-get install linux-headers-3.8.0-41

sudo apt-get install linux-headers-3.8.0-41-generic

sudo apt-get install linux-image-3.8.0-41-generic

After the update to kernel 3.13.0-27 (it was yesterday) the problem is solved for native Kubuntu 14.04 kernel.
