No, you did. I'll admit I flubbed on the negotiation between two
wide devices separated by a narrow cable. But I have personally
tried pretty much everything else I described and seen it work.
To say you `can't' do any of that stuff is Just Wrong. If you've
got some crappy parts combining some fo this stuff may not work,
but then again, if you've got crappy parts even avoiding these
combinations does not mean anything will work.

Right. And as he also said, he has arrangements like this that do
work that he uses himself.

and fast device, or whatever.
