USB port disabled

Hello krisbroui,

It sounds like your Mac's USB port has been disabled and you've already looked at the article that addresses it, right? Have you gone through all the steps there:

"If an external device isn’t recognized by your Mac and a message says that the device needs more power, the operation can't be completed, or USB Devices Disabled, try these steps:

• Disconnect and reconnect the external device to your Mac.
• Connect your external device to a different port on your Mac.
• If your external device is connected to a USB or Thunderbolt hub, connect your device directly to your Mac. 
• If your USB or Thunderbolt hub is self-powered, make sure that it’s connected to an AC adapter. 

If you still need help, contact Apple Support."

Regards.
