When I try to check my connection of the mobile with PC I am getting
following errors

[r...@localhost dev]# dmesg | grep -i usb | tail -20

Can some one suggest me on how to get rid of this CDC descriptors?

I am using fedora11.0
Kannel 1.4.3

I suspect init-string in modem definitions, is it same for all the
mobiles, or changes from one handset to another handset, If it is
generating how to change that?
