question
I just bought one of these to replace my aging Microsoft Trackball Explorer. The Kensington Expert Trackball I now have in my possession, cannot seem to operate Photoshop's Selection Tool. Is anyone else experiencing a similar issue?
I am able to use Photoshop's selection tool with this mouse. Granted I'm over a year late to the party.

question
usb 2 or usb 3?
USB 2. Not sure why you would need USB 3 for something like a trackball though. That only makes sense where you would have a device that benefits/requires the higher data rates like audio interfaces/VR headsets/high speed storage media.
