Hi,
Running under Windows 10, Calibre works fine as long as I don't connect my tablet. When I connect it, it scans the Device and SD card for books and ends up crashing after 30 seconds performing the job. I don't need to do any thing else, just connect the device and it crashes.
I have restarted my device multiple times...
I also have a Kobo Glo and I don't have any issues with it when I connect it to my computer. I can send ebooks to it with problems.
Thanks!
Eric
