It happened yesterday night. My USB mouse sometimes stops working, and I see USB device not recognized. Searching on google showed me to take AC plug off when computer is off, I have a laptop and took the power off, and the battery, and let it sit for about 30 minutes. It worked the first time. However, today morning after using it for a while it happened again. I tried the same thing and fixed it. But at evening it happened again. Is there a way to fix this?
