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.
