One of my 2 USB ports just went out. Does anyone know how I can get in there, find the problem, and fix it myself? I would rather not have to buy an expansion device for my last port. Also; what is the expected liftime of these ports? Are they replaceable? Thanks for the help.
use the "disk utility" to fix file permissions + restart; back to normal.
