New Kindle Fire HD 8 Plus 12th Gen, Calibre 7689 Error, not the usual suspects

[Nitrousbird]

The recently released 12th Gen HD 8 Plus. I've used Calibre for years, with the previous device being an HD 8 8th gen.

Error at the end of this post. Brand new device. I have done the following:
- Selected File Transfer when USB is connected, just like I did with my previous unit
- Hard reset the unit
- Updated the Kindle
- Installed the latest version of Calibre
- Tried two different USB-A to USB-C cables (one that came with the Fire and another one I had). Tried multiple USB ports
- Tried a 2nd laptop (both running Win 11), with a fresh Calibre install w/ no library
- No MicroSD card installed. Even tried installing one with no success

I can browse the file system from Windows without a problem and it appears there are no Calibre-related files on it.

Here is the error message received:
calibre, version 6.9.0

That's an error while enumerating the files on the device, browsing it in windows doesnt enumerate all files on the device. If a hard reset didnt fix it then you can try a different usb cable/port or get a replacement from amazon, or use one of the wireless connection methods described here: https://manual.calibre-ebook.com/faq...kindle-fire-hd

I've seen you give this same response to the question on many searches I've done for the issue.

But can you confirm this isn't a different issue with this newest generation of Kindle? Since it was only recently released, there may not be a lot of people asking about this yet - I've not seen any. I've already tried multiple ports, cables, and another laptop so that's not it. I know I can do wireless but prefer the wired method.

I'm afraid I am not going to spend my money to buy a new Kindle for this. MTP is a well defined protocol and on windows calibre uses the windows provided APIs to query the device, if they are failing its almost certainly a device problem.

A Fire tablet is not a Kindle. Even Amazon no longer calls it that.
