Problem: No device,RAS error, no modem

Installing new sofware for Vodafone made laptop to recognize device. However, modem driver was installed under USB devices and not under modem slots in Device manager, which made it to report RAS errors 680, 633.

Manually unistalling USB from Device manager and forcing it to search for new hardware finally made it to instal the card as modem in Device manager. After that, under Network connection - Dial up, it should be manually set to use modem driver for Vodafone. And finally, after the internal modem was disabled, Vodafone started to work.
