Furthermore, afterwards, I got the same error with the glo. So somehow the ONE messed up the program and I guess the config files. I also confirmed that the laptop was otherwise communicating with both devices (glo and one) using file explorer; no trouble uploading/editing directories on either device via USB connection.

After a number of uninstalls and reinstalls to no avail, I:
1. Used preferences/miscellaneous/open calibre configuration directory to open the config directory.
2. I deleted ALL THE FILES.
3. Exited calibre
4. Uninstalled calibre;
5. And Reinstalled and everything worked fine.

I'm a total newb, but I believe that the config files/directory is NOT completely deleted with an uninstall; hence, without the delete of the config files, calibre relies on whatever was left over from the last install when reinstalling. As the config files appear to have been corrupted in my first use with the ONE, deleting them appeared to be the only fix. Editing the config files is completely beyond me.

Hope others find this useful.
Actually, I hope no-one finds it useful. The error you received was because you hadn't updated the KoboTouchExtended driver when you updated calibre. I take it you hadn't updated calibre for a long time. There was a big change in the KoboTouch driver three or four months ago. This necessitated a change in the extended driver which was released at the same time. And that is what this thread is all about.

And a couple of points:
- The driver configuration was not corrupt.
- Uninstalling calibre doesn't touch the configuration directory or the libraries.
- A search here for the error you saw would have told you what to do: Update the driver and maybe delete a file.
