@Ripplinger and mbovenka: How big is the database file on the device? Similar reports in the past have suggested that writing small files to the device was OK. But, when larger files were changed, the connection drops. Unfortunately, the database tends to be the largest file on the device. And it can be updated when calibre first sees the device. Setting metadata management to manual on the Sending books to devices page of the preferences might solve this. But then shelves and series info won't get updated.

Also, from memory, the previous reports have always been XP machines. I don't know why. It could be older machines or less efficient drivers. Or maybe some weird interaction between the drivers and the device. But, I am also sure that moving to another PC fixed the problem. That is probably not a practical solution, unless you are looking for an excuse to upgrade
