Disappearing USB ports on Mac Pro (Early 2009)

Just a quick note before bed. Recently I've been having issues with my Mac Pro not recognizing my HiFiMan headphone amp through a USB connection. I thought it might be the amp, but I tried it on my MacBook Pro and it recognized it immediately. Tonight, I noticed that my iPod would not connect iTunes on my Mac Pro. Searching around, I found an easy solution:

  1. Shut down your computer.
  2. Unplug the computer from power and wait about 15 seconds or so.
  3. Plug the computer power cord back into a power outlet.
  4. Restart your computer.


Voila! I have my USB ports back and my system is recognizing both the HiFiMan amp and my iPod.

  2. Yep, it does seem to reoccur. Not sure why it's happening, but yes, the issue does come back after a period of time.
