You are babbling.  The goal was to find a USB hub not serving other
clients.  And apparently the one best fitting the requirements was
routed to a docking station.

Another possibility would have been to use an Expresscard with USB 3
port(s).  Obviously, an Expresscard using the PCIe lane, not the USB
connection of an Expresscard slot which would be useless unless it met
the requirement not to serve other clients.  And the USB 3 ports would
be required not because of USB 3 speed but because an Expresscard with
USB 2 ports would be a whole lot more likely to use the USB connection
rather than the PCIe lane.

A lot of people get setups like that to work without rtirq .
