How to force kinect to a certain USB 2.0 BUS

edit

I've got laptop with 4 usb BUS inside, 3 of them are usb 2.0. And I have 4 usb ports on side of my laptop, 3 of them are usb 2.0 PORT and one is 3.0 port. I want to connect 2 kinects to 2 of my usb 2.0 BUS, But no matter which usb 2.0 PORT I connect the Kinects to, they alwas goes in the same usb 2.0 BUS, hence I can only get data out of one Kinect, since one kinect will cost the whole bandwidth of a usb 2.0 BUS.

here's my lsusb results:

I want to force one kinect to use BUS 01 instead of BUS 02, but I don't know how. Any suggestions? Where can I find more information on that?
