USB_ModeSwitch

Posted: **23 Feb 2012, 10:47**

hi,everyone.I have surf the Internet with my 3g dongle.
but every time when I use my 3g dongle,I have to execute usb_modeswitch -W -I -c /etc/usb-modeswitch.conf for many times!
It's really inconvenient.
What can I do to solve the problem?any advice will help.
My system is ubuntu 10.04.

below is the dmesg log when it switch failed.
