You wouldn't get the cancel/connect popup with a charge only cable.

Also if the database on the Kobo is corrupted, you will get an error message from calibre.

I suspect the issue may be with where the ePubs are being copied.

Can @Cavin post the send to device template being used with the KoboTouch driver? It is found on the first page of the configuration dialog.

My current send to device template is:

eBooks/{author_sort:sublist(0,1,&)}/{title} - {authors:sublist(0,1,&)}

eBooks is a directory in the root of my Kobo ereaders. A directory based on the first entry in the author sort is created (i.e. Flint, Eric) and then the ePub is saved under a file name based on the book title followed by the first entry in the authors list (i.e. Mother of Demons - Eric Flint).

The attached images show my driver configuration. Some custom columns are used (kepub for deciding if I want to send a kepub or an ePub, my one collection (Finished), subtitles. estimated reading time, one used to change the series display for omnibuses to 1-9 instead of 1.09)
