Please spend a bit of time studying that 1.1 spec you have, or
actually I would recommend that you download the 2.0 spec instead:

http://www.usb.org/developers/docs/usb_20_070113.zip

Spend most of your time with chapters 5, 8 and 9.

Then spend time studying the EHCI spec. It teaches how the host
controller is programmed by the operating system.

It should become clear that what you describe just isn't possible.

Not everything that is published (on internet or elsewhere) is
actually correct.

"goes out" is not an established term in USB. I'm afraid you're not
making any sense.
