OK, got the communicating with device error again after the deleting the calibre files on the Kobo and SD Card:

calibre, version 2.81.0
ERROR: Error: Error communicating with device

CantOpenError: unable to open database file

As it happens, it seems the SD card and the Kobo are now mounted the 'right' way round; maybe it's because I powered on the Kobo before connecting?

Re the earlier comment about the extensions, oddly when I check the files onboard they only have the .epub extension, not the double extension .kepub.epub, so I don't understand why I need to add the double extension...

Restarting in debug mode:

We're about to go away for the weekend, so any more will have to wait until we're back on Sunday. I haven't really got the time to fiddle around with the side-loading process or factory resets, which is annoying as there's a whole bunch of new books that will go on the Kobo that didn't come via the Big River (and hence won't show on the iPad).
