USB Over Current Notice error

Asked By 200 points N/A Posted on -

Hi mates,

I have a Apple MacBook with a 2.4 GHz Intel Core 2 Duo processor with 3 MB on-chip shared L2 cache with 2 GB (two 1 GB SO-DIMMs) of 1066MHz DDR3 SDRAM; two SO-DIMM slots support up to 4 GB.

I got this error message while I was working on it.  

USB Over Current Notice. A USB device is currently drawing too much power. The hub it is attached to has been deactivated. 

I clicked on ‘OK’ and a  while later, the same error message came up.  At the time I had my Kingston 4 GB pen drive plugged in , as I was saving the work I did on  it.  When the error came up again on the screen, I unplugged the pen drive and restarted the computer. But still the error message keeps appearing on the screen. 

Does anyone know what the problem might be? Please share your views.

Thank you.

Bobbyh's,

 
These are some of the steps I followed, when I encountered the same problems. Hope this will work with you too. 
 
  • Connect your device to a different USB or FireWire port on your Mac. If you connect your device to a USB or FireWire hub or to a port on another USB or FireWire device, that's connected to your Mac (known as daisy chaining), connect your device directly to a port on your computer.  Some devices need to draw power from a USB or FireWire port to work; if you connect a device to a non-powered hub (one that isn't plugged in to a power source) or to a low-power port (such as the one on your USB keyboard), it may not work. If you have another known-good cable, try swapping the cable to see if that works. If it does, you should replace the problematic cable.

 

  • Disconnect all USB or FireWire devices (including hubs and extension cables) except for your Apple keyboard and mouse. Then, connect the device in question directly to your computer. If your device works now, there may be a conflict between that device and one of your other USB or FireWire devices. If you do have a conflict, you can determine which devices are affected. Connect your other devices to your Mac, one by one, making sure to test that each device works before making another connection. When you find the device that causes the issue, contact the manufacturer for assistance.

 

  • Open System Profiler (from the Apple menu, choose About This Mac, then click More Info) and then click either USB or FireWire. If you don't see your device listed in the pane, the issue could be with the device itself or your computer's USB or FireWire port. To rule out the port, plug the device into another USB or FireWire port on your Mac and then check System Profiler again (press Command-R to refresh the window). Also try resetting the FireWire bus.
 
Hope this will help you.

I have got you problem. Recently I have also experienced same kind of problem. It’s to bad to face this kind of problem with something that I love most.

Try an SMC Reset: https://support.apple.com/en-us/HT201295

Get a "pigtail"/"y" cable which has two USBconnections, doubling the power.

 

Get a powered USBhub and plug the HD into it.

 

Thanks
