I must to thank to CW team. Because they puzzled me and that way I learned a lot about USB. And regarding CW itself, of course. Yes, I spent some hours searching the net trying to understand how an USB port can suddenly stop work ... as a flash programming channel, but not for pen drive reading / writing.
Today, after a cold restar of everything, I tried two times again, at no luck.
As a last resort, being a bad guy, I suspected that CW was fooling me regarding the true reason behind the "error".
In fact, the project I had in the session was the uTasker demo.
In the same session, I closed the uTasker project and opened a MQX bases one ( of my own ).
It flashed without comments.
Moral: when CW dont like something it pretends a flash error.
