I had posted this question in the Onyx Boox section, but no one was able to help, so I am asking again in the Calibre section.

I have been using my Onyx Boox T68 Lynyx for about ten months now and I have enjoyed it. But recently I have encountered a new problem when connecting to Calibre via USB cable.

I am no longer able to add an epub to my device using a USB cable. Right click / Send to Device / Send specific format to / always results in the epub being converted to azw3 format.

To try to fix this, I have done a factory re-set. I have updated the firmware. I have done another factory re-set. Still, I can't send epub format to the device from Cailbre using the USB connection.

I am able to copy the file from the computer to the device by dragging and dropping from a file manager ... but not through Calibre.

Interestingly, I have no problem at when when using Calibre Companion. I transfer epubs easily.

Any suggestions?

Thank you
