I saw you mentioned ascm files, those are apparently not actually the books, just a token for them. Have you used Adobe Digital Editions to download the actual books?
Acsm files are not Ebooks. They are files that tell Adobe Digital Editions what to download and how long you have the ability to use the file. Download and install ADE, sign in, and then install Calibre deDRM pug in. Go ahead and double click the acsm file and ADE will download the epub or PDF. Go to where the files are stored (for me documents>Adobe digital editions) drag that book file in calibre and it will remove DRM. Convert the ePub to azw3 in Calibre and pop it onto kindle. Done :)
And this:
If someone else finds this post in 2022 or later: there’s a pretty new “DeACSM” plugin for Calibre that makes things a lot easier (especially if you try to remove Adobe DRM on Linux where it’s almost impossible to install Adobe Digital Editions).
I did install ADE first and did find the DRM epubs. I also pulled those into Calibre and saw the same thing: can’t open or convert because of DRM. Of note I have not configured the Obok plugin because I don’t have a Kobo device, but DeDRM is setup as I followed in the post above.
The second quote I can’t figure out how to use. Doesn’t seem to have an executable and isn’t a Calibre plugin as it isn’t a .zip.

Sorry if this is repeating what you already know and have tried. Hopefully it helps someone.
