My thought is that the SD card might be slower than the main memory. CC uses the network to buffer up some changes. If the SD card is sufficiently slower then calibre might time out, thinking that the device went away. The subsequent syncs would make further progress on that buffer until the buffer gets small enough to finish in the time available.

There is almost no downside in making calibre's timeout longer, so I will do that. However, it would be nice to know if I am solving the real problem.
My tablet (LG pad 8.3) was just upgraded to 4.4. I tried moving the book folder to the Android/.../files directory, and it was working fine until my SD card ran out of room. The files were not delete from the old folder, but the few hundred that were copied were visible in the program, and opened fine in Moon+Reader.

I then deleted the whole folder and deleted books with missing files to have a clean library.

I then tried copying my whole folder from within calibre. It failed out after about 150 books with a disconnected message. I tried opening the files that had copied, and everything worked fine.

If I do a couple of 100 files at a time, it works ok, but anything more then that fails after a while.

It should be noted that I have been able to copy my entire folder of several thousand books all at once under 4.3, so perhaps 4.4 is slowing things down.

Is increasing the timeout under Calibre a developer change or can I make this change in settings?

Still, the good news seems to be that once you get the books loaded, CC seems to work just fine under 4.4.
