Make sure the wall outlet or power strip you are using has power.
Check the USB data cable
■ Unplug the USB data cable that goes from the CD-Writer Music to the
computer at both ends and reconnect it.
■ Check the USB data cable for any signs of physical damage.
■ Replace the USB cable with the one provided with your drive if you
are not already using it.
■ If you have another USB data cable that you know is working, swap
cables to make sure you do not have a bad cable.
■ If you are using a USB hub, try connecting the CD-Writer Music
directly to the USB connector on the computer instead of through the
hub.
Make sure the USB port is enabled
■ If the Add New Hardware Wizard did not appear when you connected
the CD-Writer Music to the computer, your USB port may not be
enabled. Right click My Computer, choose Properties, and select
the Device Manager tab. Look for the Universal serial bus
controller in the Device Manager.
If the Universal serial bus controller option does not appear, insert the
driver diskette in the floppy drive, click Start on the taskbar, select
Run, type
A:\usbhelp , and click OK. If this program can not
enable your USB port you can enable it from your computer’s BIOS.
