Hi!
Recently I experienced that my cursor randomly stops for about half a second, and in some cases, the scroll wheel completely stops working (I have to restart the computer). Also, I ran the xperf command, and I found out that sometimes usbport.sys causes some pretty high DPC latency spikes. When I disconnect the mouse (by the way, it's a Trust MI-7770C Wireless Laser Mouse), and I use the touch pad, there is no problem with the cursor and/or the scrolling, so I think there is someting wrong with usbport.sys.
