Hi Eric, sorry for the lag, summer time...
I'm first seconding Charles comments 2014-07-09 12:31 GMT+02:00 Eric S.

I would need traces to give more info. anyway, this may not be as generic USB as you think. What I'd like to do is this: confer in real-time, perhaps via IRC, > with someone who knows this process.

Charles and myself have worked a lot on the Asciidoc conversion, with some improvements. But I know it needs an overall revamp, with usability in mind. Would you be willing to work on that one? cheers, Arno
