iMac 5k USB Kensington Mouse
Just bought and received a refurbished iMac 5k. Everything's working great, just as great as I'd hoped, except for my Kensington USB mouse.
When I plug in the mouse, it won't move.
I've searched the web for the last hour and can't find a solution. The computer recognizes the mouse because clicking works. I open SteerMouse and it indicates that it sees the mouse moving.
Yet the mouse won't move.
I've reset pram, SMC, even run Apple Diagnostics, and disk utility, but I can't get the mouse to move.
Yes the iMac came with a Magic Mouse, and it works great. But the USB mouse is my gaming mouse, with more buttons to customize.
Any solutions?
iMac with Retina 5K display, OS X Yosemite (10.10.3)
