hi, i bought a NU dvd drive , external, it uses USB power, and has 2 usb connectors, it doesnt take any drivers. i have windows sp3 and the drive only needs windows sp2. i only have one port on the right side of my notebook, and 2 on the left. but my keyboard and mouse connector only seem to work on the left side so im forced to use the right port. i have a powered USB hub plugged in to the usb port on the notebook pc, and the 2 DVD drive connectors are plugged into the USB hub. in the directions it does say that if it doesnt work you can use an ac adapter for the dvd drive ( of course its not included) windows gives me an error of

One of the USB devices attached to this computer has malfunctioned or is not recognized. please click here for help.

please any help greatly appreciated, thank you. derek

Where did you buy it? Did you check it in the shop?

If you have a powered USB hub then you dont need an extra adapter for your DVD drive. By the way I am going to ask you a stupid question, do you have any adapter attached to your USB hub?

as your 3rd port is eviedntly not working correctly, get a powered usb hub plug that into the portya mouse is in then plug ya keyboard and mouse into the hub.

use the port ya keyboard was in for yourcd driv

Did you try to reinstall driver controllers ?

I think the problem is in your usb hub,which it is only a usb hub (with no power). Try it on a POWERED usb hub, and im sure it will work.
