I've had my Inspiron 15R N5110 since January, and since probably about march or april, two of my USB ports stopped working. I'm really not sure why. I was using a madcats mouse at the time, and the mouse suddenly wouldn't work, then it would occasionally work, and now I can't use anything in two of my three ports. I've tried updating my Bios and Drivers, and I've run diagnostics checks, but the updates have never fixed the problem, and the diagnostics says that there is no problem. I plugged in my phone to both ports this morning, and the phone recognized that there was a charge, but the laptop did not recognize that there was anything plugged in. If there's any additional information needed, let me know, and tell me how to find this information, as I'm semi-computer-illiterate. I don't know where a lot of things are
