G200X schematics? was Re: USB ports ?

Ballendo,

Your'e welcome, as always.

The G200X "open source" concept has turned into a disaster because of
my mismanegent of the project. A good manager would have identified
talent, encouraged them, acted as a clearinghouse to get the talent
to work together in concert towards a common goal. It required a
good "people person" to execute that difficult job. I didn't do that
and in retrospect I realize I wasn't up to the required job
description.

Instead, my missmanagement attracted sharks and bottom-feeders. The
ones that want what has been done and even more; they didn't have the
generosity of spirit to return anything to the project themselves;
they were the one-way street kind of people. In a word, it's a mess
and I'm ready to fold it up.

It'll be taken care of the conventional way now. Be looking for it in
April. It will be very cool.
