LOL. Yeah right. Try running a stepper driver off of one.

I have a number of USB adapters that have an external power supply..so
the power needs are NOT taken from the computers USB port.

Want some links?

I want some links to some that will reliably control 3 or 4 axis of steppers
for a million lines of code, and probably a several billion signals, and
will work with just about any step direction driver.

I think you totally missed (or chose to miss) that a cheap generic USB
parallel adaptor will not fill the need.
