Bug Description

calibre version 3.27.1
operating system: OSX

When I connect my Nook, it says Nook detected. It completes Get Device info and set library information. But when it tries to get list of books on device it runs for over 4 1/2 hours, reaches 95 % and then error message comes. Up. I am including screen pics of the job details below.

Error message Detail:

Failed to delete (u'Internal storage', u'NOOK', u'metadata.calibre') with error: 2:PTP Layer error 02ff: LIBMTP_Delete_Object(): could not delete object.

That is an error communicating with the device. Usually, this kind of error can be fixed by
following the steps below in sequence. First:

        1) Try rebooting both the device and your computer
        2) If that does not work, find the files driveinfo.calibre and metadata.calibre on the device
           and delete them (you can use Windows Explorer or a file manager on the device itself to do this)
        3) Reset the device

If none of those work, you can use one of the wireless communication methods described here:

I was able to deregister and erase my nook, when I did that the next time I reconnected it worked, I was able to send the books I wanted for calibre. But when I went to reconnect it a second time the same error stated above occurred.

Ok, thank you.  It is strange because it is happening on every glowlight 3 I own, which is why I thought it was a bug and not the device.

There have not been any changes to that driver in calibre in years, and
the issue you describe is intermittent, which is a very strong indicator
of hardware issues.

So sorry to bother you again.  But now I am getting this message on my third Nook Glowlight 3 when I try to send a book.  Is this also a connection issue?  It is odd that all three of my Nooks would begin failing at the same time.

calibre, version 3.27.1

Yeah, that error means calibre asked the device to create a folder and
it failed. As I said, you can try resetting the device.
