I just encountered a problem I have not seen before.
I have a current version of 64 bit Calibre, installed under Windows 10 Pro. I have an HP 7 Plus Android tablet running Android 4.4. My eBook library on tablet is on an external 32GB microSD card, and I use FBReader fo Android to view books on the tablet.
I connect to the tablet using a USB cable, and the tablet connects via MTP. When I plug in the tablet, Calibre sees a device is connected, and begins the process of looking for eBooks. That takes a fair bit of time, since there are thousands of volumes on device, so I do other things while I wait for it to finish. Once it's done I see Calibre's book list with checks beside volumes on device, and I can transfer new books and perhaps remove books currently on device.
Today, Calibre crashed and burned when the device was plugged in and it was searching for volumes. I got a Windows dialog box stating Calibre.exe had stopped working. In Windows Event Viewer, I saw
Code:
Faulting application name: calibre.exe, version: 2.85.0.0, time stamp: 0x591532f6
Faulting module name: wpd.pyd, version: 0.0.0.0, time stamp: 0x591532e8

Report Id: b830ef6f-f929-4aab-8e15-36580d1f56bb

in the application log.
I restarted Windows and the tablet. I ran a file systems check on the volume where the Calibre library lives on Windows and it came up clean.
I shut down the tablet and ejected the 32GB microSD card, plugged it into an adapter, and ran a file systems check on it from the desktop. (The card is formatted FAT32.) That came up clean.
I restarted everything and tried again, and Calibre once again crashed communicating with the device.
What's the best way to debug this? Is there a good way to determine why the crash is occurring?
Looking at other threads here, I see that removing the Calibre metadata file on device and rebuilding might be a fix. I can do that if required - it wouldn't be the first time.
Suggestions? Comments? (NB: "Use wireless to connect to the tablet instead of a USB cable" is a
very last resort matter. This has been working fine till now, and I'm averse to redoing my setup unless nothing else will work.)
Thanks in advance.
