Windows Xp prompt me the error "USB Device Not Recognized" when i plug in the Pioneer DVR-111 External DVD Writer to the USB port (tried all the usb port in my computer). Windows Xp recognize it as an unknown device.

I have no problem when i plug in the same device to other computer which is also windows Xp.

Does anyone know what is the problem?

Did you try installing the drivers first.  Some USB devices tell you you must install the software first, then plug in the device.

Disable power management of the USB hub.
Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, and then click Run.
2. Type devmgmt.msc in the Open box, and then click OK.  
3. Expand the Universal Serial Bus controllers node, and then follow these steps for each USB Root Hub that is listed: a.  Right-click the USB Root Hub, and then click Properties.  
b.  Click the Power Management tab.  
c.  Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.  
 If not the solution...post back...T

USB extension is a quite common tool right?

USB extensions seem like they would be common place; but they do not always work as simply as they should be.
It has to do with I/O from the product to the computer and the way it travels. They will not work for PDA cradels (older ones), RW drives (CD or DVD burners) SoundCards (external laptop style), and some mass storage devices. For these items (if availible) FW 400/800 works much better.

In the future, just remember that even the simplest (seeminly) thing can be the boulder in the road between you and IT happiness.

it can, be a common tool, but what you do not seem to understand is that we have no crystal ball here, and have to go upon what YOU tell US. Nothing else.
