For a long time now (2 years?), both of my USB ports on my Macbook Pro (v.10.5.8, 2.4 GHz Intel Core 2 Duo, 2 GB 1067 MHz DDR3) have been faulty. I'm not sure when it happened, but they both stopped working consistently. However, I rarely needed them and only used it for a mouse, which when repeatedly plugged in, eventually would work. Furthermore, on that side, the headphone jack is also there and takes a lot of tweaking to get to work. Is it a hardware issue with my Mac? And what do I do to fix this? I'd rather not go to the store and get the computer taken apart and redone.
