Seemingly, out of nowhere my Laptop mouse started acting very erratic. I tried my desktop mouse…same thing! It didn’t take long before I realized it was the fat Lexar USB flash drive crowded in next to it. I even switched the USB slot…same thing! Mouse worked fine once I removed the Lexar. A USB extension cable seemed to fix the problem.
Re-checked it and it’s not crowding the other USB slot, at least if I put it in straight. It worked fine. Perhaps I didn’t put it in straight.
