The USB-IF kicked the Linux Foundation out of its organization a number
of years ago for an unknown reason.  Unknown to me, the USB-IF
representative of the LF, odds are people within the USB-IF know why
they did it, but they wouldn't tell me.

We were even _paying_ them to be part of their group and they kicked us
out (without refunding our money), I can take the hint that they don't
care at all about Linux...

Yes, a list like that would be a wonderful thing to have, but unless
something radically changes within USB-IF, I doubt we will ever get such
a thing :(
