How to solve the "8020" connection problem with N1MM Logger

Since I updated my laptop to Window 7 I'd had a very nasty problem with N1MM Logger: the rig connection is lost all the time. I figured out (thanks Go...oogle :) ) that the problem was in the USB-to-serial interface. Microsoft has documented this problem:

The simple solution for this was to update the virtual com port driver. The steps:

1. Open Control Panel->Device Manager
2. Select Ports and double-clickc there at your virtual com port
3. Select the Driver tab
4. Click Update Driver
5. Hopefully the automatic update will solve the problem for you. Otherwise you have to download the driver from the device manufacturer's homepage, and select manual installation here.
