Calibre is the current 3.40.1 version, running under Win10 Pro v1803 with current patches.
The device is an Alcatel Fierce 4 phone, running Marshmallow 6.01. Transfer is via USB->MicroUSB cable.
Books are stored in the /Books directory in internal storage. They currently occupy1.3GB. The device claims there is 4.04GB storage free out of 11GB total.
Calibre connects to the device and returns existing volumes on device. Trying to add new ones returns
Code:

I've rebooted the device, restarted Calibre, and tried several different USB cables and plugged into different USB ports with the same result.
I've also removed several large volumes from the device, in case I'm running into an odd out-of-space issue. (I doubt that. Available storage seems to be one large pool used by everything that can store to device. The built-in camera has no issues storing JPEGs under /DCIM.)
Any suggestions on how to further debug this? This
used to work.
