Then why does the description of the forum called DEVICES say it is for:
Troubleshoot installation and connection issues specific to your device or OS, and learn how to make the most of calibre's device integration features
Also I initially posted in the Kobo forum. If you clicked on the link in my post you would have seen that. I never got any response from you in that forum so tried posting here thinking according to the description this was MORE appropriate.
Does this mean that you have no solution for the problem? If so just say so.
Thank you for you time.
