If you get the book from a place like eBooks.com or Google, you'll download the ACSM file. On your computer you can use Adobe ADE to download the actual ePub book (if you're not using Linux, there is no ADE for Linux). PocketBook and (I believe) Tolino allow you to bypass ADE (on your computer) because they have it built-in into their eReaders. Sony used to do this as well, years ago, but their certifications weren't updated and that feature is no longer available.
I believe Amazon uses their own system for DRM protection.
Kobo can use ePub. KePub is just their "enhanced" ePub. I believe you can change the extension to ePub and use their books on other eReaders. (if the DRM protection is disabled.) PocketBooks actually have two readers built-in. One for ePub 2 and one for ePub 3, which has some newer features. Normally it's just handled automatically, but if you press and hold on the book cover, you can choose which reader software you would prefer. I believe PocketBook uses the most advanced ePub "engine" — RMDSK — in eReaders (but I don't know a lot about it). Kobo has gone with their own ePub enhancements (KePub) but can use standard ePub books as well. I think all eReaders (besides Kindles) work with ePubs
Sorry for rambling. I'm sure others can explain this more clearly than I have.

Thanks. To clarify... (Still confused on #1-3.)
1. Do I WANT only ASCM files? I thought epubs were what I wanted to send to a Kobo.
2. If I get a book from Google or eBooks, then I want ASCM files? No other file formats? Then download Adobe ADE to my laptop and use my laptop to do something to the book before sending it to the eReader (PocketBook or Kobo)? Confused on this one.
3. PocketBook has built in ADE so nothing to do if I download a book directly to a PB device. If I use my laptop to download a book, then the book has to have something done to it with Adobe ADE before I send it to a PB device?
4. PocketBook uses epub2 and epub 3. I read that one of those allows for zooming in to maps, etc.
5. Nook uses epub.
6. Kobo uses epub and kepub.
7. Amazon uses KFX currently. (AZW3 for older books.)
