Screen Shot 2013-06-28 at 22.40.56.pngHi All.


When I logged on to my computer this evening and I was on skype, I clicked on a link to view something and this popped up on my screen.


I don't have any USB devices plugged in to my computer. So what is this and why is it showing? Any Idea anyone? and what should I do about it?




iMac, Mac OS X (10.7.3)

    Hello Tricia,


    If you have no USB devices connected, not even a keyboard or mouse then the only thing left connected to USB is your internal iSight camera, which may have been called on by Skype when you clicked a link. Restart your Mac and open the Photo Booth app to see if the camera works ok and gives no similar warnings.

    You probably need a powered USB hub to support the unpowered USB devices connnected to your iMac. These devices can be things like cameras, printers, etc...

    Thank you Jayv.


    I didn't think of my Mouse or Keyboard Duh!!! but they are always on anyway, so didn't enter my head.

    Looking at Rkaufmann87's answer as well. I think you are both right.

    It could be that skype drew power,  and on mention of a printer I checked mine,  as there is no light on telling me the power is still on,  I checked it and it Was on.  Now switched off


    Thanks Again.

    Thank you rkauffmann87.


    I'm glad you mentioned the printer, it woke me up to the fact it was switched on, I really must remember to switch it off, once i've finished with it.


    Thank Again.
