For me, it doesn't seem to matter if I use a USB 2 or 3. It happens with both randomly. Sometimes it happens when transferring books, sometimes when first opening Calibre, sometimes when trying to check the database... And, yes, the device disappears from the list of drives when it happens. It's very frustrating, especially because it doesn't happen with anything except Kobo devices. I'm not blaming Kobo (entirely) but the interaction between Windows and Kobo is not working correctly, and I'm not sure what the problem is.
