I tested manually mounting the device and writing/creating files from console. It works well. Also, after unsuccessfully attempting to use Calibre to copy the files, I can still write/create files manually from console. I don't know if that helps to diagnose the problem.

I only understand the surface of that, so I'm not really sure if there is something wrong there.

I'm not sure if the read only warning is relevant, because the data disk is the usb0.

My /var/log/messages reported while connecting the device:

This looks like the dmesg stuff, to be honest I did not check if they are exactly the same.

I'm still clueless
