If you can post a picture of your setup that may help.

[CLOSED] USB power error when i connect my cdj400 to my Macbook
Recently bought a Macbook to run Traktor on.
I want to intergrate my CDJ400's and my djm400 mixer.
But with setting up it goes wrong. When i connect 1 USB cable from the cdj400 to the USB port on the macbook, i get an error message wich saids USB port is using to much power. ANd the macbook disables the usb port. Did some reading on the internet, wich said i should connect the the cdj400's to a powered usb hub. But i get the same error message. So i am guessing that it's some sort of setting that is wrong. But scince the macbook is pretty new to my i have no idea where to look.

I use an A to B usb cable to connect from the back of cdj400 to my macbook.
I run Traktor pro 2.5.1
I updated my CDJ400 firmware to v1.33

@Jos > Have you tried using different USB cables? Does this happen with both units?
There are some threads on the Apple forums about these kinds of issues. If you used a POWERED USB hub then the problem might resolve. I'd try new / different cables first. Then perhaps consider resetting the SMC / testing the hardware etc

Like said in the first post, when i use a powered usb hub it gives the same error messages.
the 2 cables i am using, i bought them with the Macbook. So they are new. And it happens with both units.

Ok, then you might have to try some troubleshooting steps on Apple support community.

It seems i have an unique problem, after 2 weeks still no replies at the Apple Community forums

I guess your other option then is to invest in a powered USB hub.

i am using this USB HUB http://www.sweex.com/en/assortiment/connectivity/usb-firewire-hubs/us018/
the power supply is 10 W en the CDJ400 needs 19 W
http://www.pioneerelectronics.com/ephox/StaticFiles/PUSA/Files/CDJ400_GSpecs.pdf
So if i use 2 cdj400's i need minimal 40 W supply
am i right?

Did a little testing, and hooked the CDJ400's to my old laptop with Windows XP.
It recognize them right away, so it is some setting in my Macbook or the USB hub is not working right
