I have an HP Pavilion P6150t desktop PC. The front side USB ports stopped working a few weeks ago. I have 8 ports showing (working properly) in Universal Serial Buss Devices ( I added an additional 3.0 card during the last year). I do a lot of photography, and have always used the front USB ports to download photo files from the camera. The front side card readers are all O.K. All the back USB ports are fine.
How do I go about checking these two front USB ports, and resolving this issue? I did replace a bad optical DVD drive in this area recently. It's working O.K., but is in close proximity to the USB ports. Thanks for any thoughts.
