I have a Dell Latitude E6520, running Win 7 Pro, SP1, 32 bit. The USB ports have stopped working. They do power things up, like I can charge my cell phone, but they do not recognize any devices that I plug in.
Previously. This happened once before and I was advised by Dell Support to start into safe mode, then Admin mode, then log in regular. It worked and the USB ports started working.
I tried that this times and they did not come back. I have run several anti-malware programs and everything looks clean. Also, i have went into the device manager and made sure all of my USB drivers where up to date
