    "The USB device is currently drawing too much power.

    The port it is attached to will be deactivated"

    As of last week, this message pops up when I plug in my digital camera cord. I tried all of the plugs, with and without other things plugged in and this message still pops up. I thought it was the cord but I tried a new camera cord and it's doing the same thing.

    I have an Intel Mac, 2.16ghz, 1GB. It's 2 years old and has never had this problem before.

    I've tried rebooting twice and it's still doing it.

    Anybody have this issue and/or know how to resolve it?

    Has this camera worked before?

    If you use a powered USB hub it should work fine.

    I am having the same problem except that port doesn't work. Have you found an answer on how to fix it?

    Do you have another computer you can plug it into so you can isolate the problem to the camera and/or cable or the mac? It's kind of sounding to me like your cable has gone bad, but really can't make that determination without isolating it.

    I do but unfortunately it is not the cables because nothing works in that hub :confused:
    I have used the cables in my other computer. it all started when my 13 yr old used a mouse in the mac. It was working fine for several months and then went dead. So i bought an Apple mouse thinking it was the other one and this too did not work in the hub. I hope that helps.

    This is a Mac OS X problem and has nothing to do with the USB device

    Same msg: "The USB device is currently drawing too much power. The port it is attached to will be deactivated" appears as has been reported by those with Camcorders, cameras, etc. My issues is a heasset that worked fine for a year, works on a PC I have, but gets the above message on my Mac.

    The focus of responses (sensibly, i suppose) focuses on the device...but anyone looking as this USB "too much power" issue can see that there is a pattern. However, I find no solution. Can anyone with greater diagnostic skills help?

    It sounds like the device is trying to draw the full 500mA without identifying itself to the host, which is (from what little I recall of the USB spec) in violation of the standard. Does the Mac recognize the device in any way when you get these message? (i.e. does the Mac appear to see the camera? Can you transfer photos, etc?)
