First USB port stops working after random time and won't work until I restart

I've a late 2011 15" and use both of my USB ports for my clone drives. Both work just fine. I'm not so sure that it's a software problem as I'm running ML as well and having no problems. I keep one USB clone drive (my 'current' clone) hooked up 90% of the time with no problems. It could be a hardware problem - only way to find out is possibly to run anApple Hardware Test. If you come up with errors, you'll know. If no errors, you'll just have to take your unit to your local Apple Store and let them run further diagnostics.

Good luck,

I've had to use option-D sometimes - D usually works. You have to keep it held down for a long, long time.

But this icon should (usually) show up:

Give it another shot - it seems as if the error you received was some sort of Apple serever error.

You don't have to be from the US to have your Macbook repaired. As long as your Macbook is still covered under the Apple Care warranty and it is registered under your name, you can take it to any Apple Store or any AASP.

As for the diagostic tool, unfortunately, the Apple Hardware Test does not check the USB port but it will test the logic board that it is connected to. Only Apple certified technicians have a more comprehensive software diagnostic tools to determine if any hardware is malfunctioning.

Have you checked for an Apple Authorized Service Provider in your country - https://locate.apple.com/country?

They're pretty much all over the world...

Hey guys

I have this problem on my late 2011 Macbook Pro 13 inch,

It's been for a year already and it really freaks me out and drive me crazy

My first USB port next to the thunderbolt stops working after like 3 days, and it won't respond until I restart my computer or log off and log in again.

If I restart my computer, USB stops working after 3 days and won't respond until I restart

If I log off it works for like a couple of hours and then stops again...

I'm sure this isn't what you want to hear but unless you really are using your laptop 24 hours a day, is there any reason why you don't just shut it down and reboot when you're ready to use it again? I have to wonder how many other MacBook Pro owners potentially have the same problem but when they quit computing for the day, their computers quit too.
