When i plug my nikon coolpix 4600 into the USB this message pops up: power surge on hub port. How do i fix it?
A USB device has exceeded the power limits of the hub.
What could be causeing this and what can i do to fix it, i need to get the pictures i have on my camera to the hard drive asap.
Is the camera plugged into a hub? Or did you plug it into the USB port on the computer. A hub is a piece of hardware that is connected to an USB port (to the computer). Basically if you have two USB ports on your computer, a hub will give you more ports (think of it as a splitter at the end of an extension cord).
Unfortunately some hubs are not "powered". Each item plugged into the hub draw a bit of power from the computer, and you basically overloaded it. Nothing is broken--but the item in this case your camera, didn't work. You need to use a hub that is powered (that comes with its own power supply, something like 5 volt DC).
I hope this helps a little. Meanwhile, plug the camera into an USB hub on the computer instead.
