Thanks, guys for the responses.
Such a simple thing, yet how complicated it has become.
First, being in koreader, couldn't connect to the PC via USB. Powered off and back up into KSM, chose USB. This put me in Nickel, and got connected OK.
Second, my font is Museo Sans 500, and it only has one .otf file - no italic or bold. After putting that in a folder in the Fonts dir it didn't show up in the list of fonts. Placing the .otf file directly into Fonts worked, and it showed up.
Third, my H2O2 doesn't seem to like Museo Sans 500. It appears to be defaulting back to Publisher's, even though the Font Face shown is Museo Sans 500.
Before getting into koreader I had successfully installed Verdana on the device, and it works well.
What am I doing wrong?
Edit: found the path .adds>koreader>fonts, and added the folder named museo.
Now how to change the font used by koreader to one where lower case g doesn't look like an ant.
Edit2: Can someone give me updated instructions for this?
