My wired optical mouse installs as unknown device on my Lenovo E 531 (6885TU). The mouse is a Optical 7d 2400dpi. I tried UPDATING my drivers but the same kept happening.Where you getting the drivers from ? ?A new WIRELESS mouse would be 20-30 Bucks BTW...I get the drivers from the lenovo site.
Is there specifically a certain driver I'm suppose to have?
If so, could you give me a link.
From the Mouse manuf. site,,,So, what would you recommend?Go to the website of the mouse manufacturer and download and install the appropriate driver.The mouse doesn't have the manufacture NAME nor logo.

Based on that alone i personally would buy a new mouse...Well, it seems to work on my other laptop (compaq).Just got a Onn Wired Mouse. It lights up but the mouse won't move and the right and left clicks don't work. The driver does install correctly.With the limited information given, here are your options.
1. Buy or borrow another mouse.
2. Buy a wireless mouse.
3. Buy another computer.

The generic mouse driver in Windows works GOOD most of the time.  Using different drivers does not OFTEN fix a hardware issue with the USB ports.
I'll try another mouse.
Thanks anyways.
