Calibre crashes when it finds Cybook Odyssey

Everytime Calibre finds my device, a Bookeen Cybook Odyssey (why 3 names??), it just crashes. It's the only device I have around at the moment so I don't know if it's specific for just this device. The device icon appears in the menu and a little bubble shows up in Windows saying that Calibre has found the Odyssey. But then Calibre just crashes. No information as to why this happens.

I turned off automatic copying of news to device, but it made no difference.

Vista sp2, latest version Calibre, latest version software in Odyssey. Same behaviour after updating USB-drivers.

I don't know where to start searching.
