I had posted this message earlier. Unfortunately it was not put up on the forum.
I have recently updated form Suse 11.1 to Suse 11.2. When I connect the above USB modem it is recognised by the system and I configured through yest>network>modem.But it did not work. Then I used wvdialconf and could get connected only once through wvdial. But subsequent connection fails. Each time I connect it to the system it gets attached to a different ttyACMn where n value varies from 0 to 7. So if want to dial I have to use each time the commands
#>wvdialconf /etc/wvdial.conf
#>wvdial
It initialises the modem but the connection fails with the following message

I have tried all possible suggestions given on this forum including installing latest version of usb_modswitch.
I have switched to Linux a year back. Please provide some expert help?
Thanks in advance.
