Congratulations to ME !
At first (many months ago),
I found pushing books FROM Calibre to Koreader*
and pulling them TO Koreader FROM Calibre**
difficult and frustrating !
But today I gave it another go and it turns out that what I learnt back then really made it so much easier.
I've now got things set up so that pushing or pulling a book takes SECONDS!
FANTASTICO!
It's actually pretty easy once it's set up!
SIMPLE BUT POWERFUL TIP
One useful thing I found:
In my personal database (Evernote)
I made sure to put the instructions in TWO different sections:
1. Daily use
2. Set up
If you don't do that, it just creates a mess, which is one reason it's taken me so long to get to the point of being able to do this routinely!
............
Anyway, I'm really glad I finally tackled this because I know it will be so much easier than struggling with USB cables!
