I have had this device for about two months and so far did not experience any trouble with it talking to Calibre. Now, out of a sudden, it stops working, every attempt ending with this dreaded error message. The details are as follows:

Failed to upload file named: driveinfo.calibre to (u'Internal storage',): 2:PTP Layer error 2002: send_file_object_info(): Could not send object info.
2:Error 2002: PTP General Error

This is on calibre 4.12.0. Neither the device nor calibre where upgraded recently and there are now other changes either, except that I have been reading on the device.

I tried the obvious things like rebooting the device, the computer, I even removed the calibre device and metadata files because they might have been corrupted, but there is no way getting around this.

Any advice on how to proceed here is appreciated,

All the best,
