Comment 6 for bug 1781922

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.

 It's likely your Nook is failing, you can try reseting it, but most

Title:
  get list of books on device (nook) crashes

Status in calibre:
  Invalid

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:
