It works everytime, when using in Calibre a virtual library with app 6000 (from my more than 16.000) books and ending it when connection is completed.
So, I know a workaround.
I am 99% sure. The calibre exception (timeout) says "Device did not respond in reasonable time" which means calibre was waiting for the device. There isn't anything the calibre driver can do if the device doesn't answer.

Back when I owned CC, these situations arose when the device put itself to sleep during a connection. Later versions of android are extremely aggressive about shutting down apps that appear to be doing "background" things. The more books on the device, the longer the "background" task runs. If I were you I would try turning off battery optimization for CC, and possibly extend the screen "sleep timer" to very long.
