USB exceeding its power limit

Twitus · 05-12-2008, 04:52 PM

Hi everyone,

I have bought a laptop about a year ago. I have only internet and a mouse connected to it. Everything went well for the whole year, until I recently started receiving the following message:

"USB device has exceeded the power limits of its hub port"

Both the mouse and the internet are now down. I've checked the ports and Windows tell me they are fine. I tried the "uninstall/reinstall" technique proposed in the "help" section, but it did not work.

I did not change anything recently, so I am wondering what could have created the problem, or even if it is software or hardware related.

Any suggestion you may have would be greatly appreciated! Thanks!

If the only USB device attached is a mouse it would likely be a hardware problem. First see if the message appears with the mouse attached. If so, borrow another mouse from someone. You must know somebody with a USB mouse, right? If the message does not appear, then there is likely an issue with the mouse and for some reason it is drawing too much current. If the problem persists with or without the new mouse then there is more than likely an issue with the main board and that means a trip to the manufacturer for repairs.

Thx for the reply. I already tried and it still does not work. The problem is also with the internet connexion (which uses another port).

If you have a copy of Windows that can be used to reinstall without destroying your data you might try doing that. Sometimes it comes in the form of Update or Upgrade to the software. If it is an emergecy disk, see if it will permit a non-destructive reinstall. Check the manufacturers web page for the specific model and find the drivers for your computer. Download and install all of them. All. If this does not sove the problem then it has to go back to the hardware, be it the mouse itself or the voltages on the main board.

If the above suggestions don't work, you might be able to get around this by buying a powered USB hub.
