However, while I was looking for things to try I think I have found something. I clicked on Library and moved my library to a new location. This restored the Calibre database and in the process found some problems - namely 'Primary Key must be unique'.
Anyway, that is what I think I did! I know, I should have noted all the steps down as I did them...
Here is the log
calibre, version 0.8.61

All 3 books have been in my library for some time, so can't see why they might be causing the problem. And this may be totally unrelated. I think some books may have gone astray during the restore, but as I have nearly 4000 it won't be easy to check this.
Sorry I did not post the debug log for My device is not detected but for whatever reason it is now working again. Hope it continues to do so.
