My seemingly non-working USB port now recognizes my devices. So, this worked for me and my USB started working again, what a relief! Hi Guys, after reading all the responses, first off, if the above stated solution works, then good. Now, some responses were, that one should throw the logic board in the trash, bad idea.
Easy solution, replace all the filters for each port or just the ones on the data line. USB ports fixed. Yes this is quite technical and maybe only suited for an electronics engineer, but I am not and I can do it. These kind of repairs are easier than one would think, there is still hope. Can you make a video on this?
Or at least a very detailed photo-document? Thank you so much! I have a razer driver that was not working but now works, and my drawing tablet works now!!! Luv u!
This worked like a charm for me, thanks. Thanks so much!! I thought I was going to have to pay apple to fix it since I didnt have apple care! Thanks so much. Wow—this totally worked!!
How to Reset USB Ports on Mac Laptops
Your advice saved the day. Both ports stopped working and I needed to use them for a deadline project. So I had the same problem with USB ports not working on a macbook pro. I tried restarting the computer, updating software None of that worked. The screen flashed white and gave the start up sound then went back to black four times before I let it go, then I started the computer and logged back in as normal to find the USB ports working.
Or just, you know, call apple. Fixed my problem in about five minutes.

Part 1. Fix USB Flash Drive Not Showing Up on Mac
Thanks guys! Took a couple of restarts before I got it right but it worked. This worked like a charm guys! Worked on my Mac Pro Then when releasing buttons, it changed to green briefly then back to orange because it was not fully charged. Thought I did it wrong first time so repeated the process; same observation.
My mouse is a cheap Logitech. And I was sure the USB port was not working by testing w the printer input cable between my two ports. None of these resets worked. Any ideas? What sort of Apple-paid hack are you?

I tried the PRAM reset, too. Anyone else have this issue? Late MacBook Pro 5,1.
