Mouse optic sensor keeps dying

I assume your mouse is wired. is that correct?

Look at the back of machine for a USB port with a black tongue, not blue, red, yellow. Black is USB 2.0

Running out of ideas.

Read anoth Steel Series thread. Suggest going into device manager and under Universal Serail Bus look for USB Root Hubs. Look at properties for each and set Power Management option to disable.

One other suggested showing all hidden devices under Mice in Device manager and deleting them all. ( Think you done that)

No guarantees.

I would establish return policies.

I know we each have our preferences for certain gear but I might be looking at another mouse.

I saw a lot of problems with this mouse and the manufacture, in my opinion, doesn't seem interested. If this mouse listed as suport under Windows 10?

Maybe even put the issue back in their lap and ask them what info they need to identify issue (Dumps, traces, environment info)?

Oh, thought you were on 10 as this is the TenForums. There is a seven forum although I think you will find the same members.
