Found the culprit! On my second machine modemmanager (D-Bus service for managing modems) was missing. Installed with Synaptic and it now works. I have no idea why modemmanager was not installed on this machine. Anything to do with Betavine? I don't know. To summarize: Huawei E620 USB Modem does not work on 2.6.31-20-generic #58. Upgrading to 2.6.31-21-generic #59 through Update manager solves the problem. Info for people living in Belgium: the Huawei E620 USB modem is the one that is provided by Belgacom Mobile (or Proximus) identified as Modem USB VMC K3715 or 'Vodafone Mobile Connect' so they know it works with Ubuntu 2.6.31-21-generic #59. I my case I have a Proximus Mobile Internet subscritption. I want to mention it as it is not documented in the documentation.
