Comment 2 for bug 2000877

I've added this already to https://bugs.launchpad.net/calibre/+bug/1953155 but here it is again:

To address the steps in the linked section of the FAQ:

- It's the only device connected. When connecting a different ereader (Tolino Shine 3), it shows up immediately in Calibre
- It is not an Apple iDevice
- It is an Android device that uses MTP. I can transfer files using the app OpenMTP. When I open Calibre first, OpenMTP doesn't detect the device (just confirming that only one application can access one MTP device at a time). Calibre does not detect it at all, even on a freshly booted system with no applications opened.
- There are no permission errors
- I'm running Calibre 6.10.0
- The device does not show up in the Finder. This is, however, no surprise as MTP devices never show up in the Finder
- The "Ignored devices" section in Calibre is empty

Here's what I think is the relevant part of the device detection debug output:

USB devices on system:
[

  '0x8000',
