Well your USB configuration looks a lot better. Sorry it didn't fix your mouse stuttering issue.
Have you tried using the mouse on another system to see if it has the same issues?
I assume you have tried using a number of different USB ports since you exported and installed the USBPort.kext in your system.
You are using a USB Receiver for the mouse. Where is this located, in a port at the front of the case or on the rear I/O plate (hidden below a desk)?
I had some issues with my Logitech Mouse/Keyboard (more the keyboard) and ended up using a USB extension cable so I could position the USB receiver at the base of one of my displays.

Some Keyboard & Mouse combos come with a USB extension cable, my Logitech set did and that is what I use.
