I'm posting some snips from a Tumbleweed virual machine. One shows the Kindle device as mounted in the file manager and the other is the text output from running calibre-debug -d (wrapped in spoiler to keep the message easier to read). This shows the 0x1949 vendor ID from Lab126 who are responsible for the Kindle ereader firmware.
Spoiler:
Code:

Hope this is of some help to you.
Edit: From a terminal session, try running df and see if it shows your Kindle. for me it shows as:
