Please tell how you used Procmon to debug this

  1. Download procmon
  2. filter a thumb drive
  3. Eject
  4. make note of it
  5. remove old filter, add filter for your filesystem device
  6. Eject
  7. Whats different?
    If nothing then broaden the scope (registry, other device, the process doing the eject and so on)
