USB Drawing too much power

[Samantha124]

So everytime I try plugging something into my 2011 Macbook Pro I get an error saying something about the usb is disabled because it is drawing too much power. This happens with my Nook, iPhone, iPad, Fitbit, pretty much everything. But yet strangely it will charge the stuff it is just that the Mac won't acknowledge something is plugged up. Anyway that is with one port. The other port is completely dead.

I tried:

• Resetting PRAM
• Resetting SMC
• Clean install of OS X

Do you guys think this is a hardware issue at this point? Maybe it is time to retire it but I hate to because it is still a decent computer. I've googled it and I'm pretty much not getting anywhere.

My guess would be hardware, but I could be wrong.

You may want to try the Macbook Pro subforum rather than the Macbook subforum.

Alright thanks just realized I posted in the MacBook area instead of Pro area.

Clean install of OS X, but did you try cleaning the contacts in the port?

Using some finesse, you could use an alcohol swab to clean them.

I cleaned the ports with alcohol and a swab. It's still not working. It's weird it still charges items.

Ever have a storm and outage while using the Mac, and not using a good UPS and/or surge protector?

New USB cables, devices?

MacIntouch is having a run on USB issues with Macs and OS X

I am good about charging it only with a surge protector. I've tried a huge variety of cables and devices. All that happens is one port will charge it but not recognize it.
