I'm trying to use a D-Link DWM-156 3G "dongle" on Debian Wheezy.I've tried to "UPGRADE" kernel from(3.2 to 3.12),But that's not effective and problem still exist.Now after reinstalling Debian(3.2 - 32bit) and install both of "USB-ModeSwitch" and "USB-ModeSwitch-Data" i get some error at OS boot up process (/var/log/syslog).

Somthing like below :
