How to re-enable USB Port

[rlucen79]

Hi, one of my usb port is unable because a usb device is drawing too much power.

I've tried without success resetting the mac's PRAM and NVRAM and resetting SMC.

What else i could do?

I have a macbook pro 13 OSX vs.10.7.4 Intel processor.

Tks!!

Use a powered hub.
Make sure any devices that have an external power supply are using them.
Plug individual items in until you identify the one that's drawing too much power.
Try the other USB port. On some macs one of the USB ports is a high power version that allows for charging iPads, etc.
