@picree: The package in the first post hasn't been updated in a while.
The code on github is up-to-date, though, so just clone/tarball that and install it manually. It's just a KUAL extension, after all, you just need to make sure it's in the right place
.
As for the Calibre plugin, current versions should detect the Oasis properly. Although autodetection is possibly broken on Windows 10 right now. I haven't had time to look into it yet, and probably won't for a while, since Win10 AU is being a whiny bitch on my desktop, and magnificently BSODs without logging...
