USB port drawing too much power. The device that is plugged into it will be deactivated. There are only two things plugged into the USB-The keyboard and mouse. When I get this message, the mouse freezes. If I jiggle the mouse cable where it is plugged into the USB, it comes back and everything is fine until this message comes up again.
But in this case, if the power management is deciding there's too much power drain from the get-go with nothing plugged in, there definitely is something wrong. Mind you, some of the components on the Mac are internally connected to the USB infrastructure, such as the trackpad, camera, etc. I'd suggest the following:
It's probably due to USB draining too much power from the outlet as shown. If you connected through a hub, connect directly to the Macbook, or you have damaged either port or the USD cable or device. Try connecting to other port/ Mac/ PC to check or external powered one, Eg: External Powered USB HDD.
One of my USB ports is being constantly disabled by my OS because it is drawing too much power, without a device attached. Is there any way to permanently disable the port?
Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled. To prevent damaging your computer, the USB device drawing too much power has been disabled. Other devices may have also been disabled.
We have an issue with an Apple Mac Pro (circa 2005/6) that even with no external USB devices attached, including mouse or keyboard, it is telling us "USB drawing too much power". We've reset the PRAM, NVRAM, removed the battery, reseated cards/plugs, etc. Message keeps popping up. Rest of the Mac seems to work fine.
When plugging into the usb ports, a popup window says it has been disabled because a device is using too much power. I've tried resetting the SMU, PRAM, disconnected the battery for 10 minutes. Nothing works. The only other advice I've read is that the logic board may need to be replaced. What can I ...
To solve the problem, I unplugged all my USB devices and got nothing. I then simply uninstalled the driver and reinstalled it from Intel; the problem resolved itself: I didn't get the message again. I booted to Mac and got the "Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
Symptoms such as these could mean that a device connected to the USB-A , USB-C , or Thunderbolt (USB-C) port on your Mac isn't getting enough power:. A message says that the device needs more power, the operation can't be completed, or USB devices are disabled until you unplug the device using too much power.
It could be a corrupt USB kernel extension. I'd try booting to Safe Mode:. Turn off your Mac. Turn it back on and before you see the Apple logo on your screen, press and hold the Shift key until the Apple logo appears.
