USB 2.0 interface cable
# The USB model comes with High Speed USB2.0 cable, which is
capable of burning or copying DVD or CD at the maximum
speed of the drive.
# Since USB 2.0 Hi-Speed is an evolution of the existing USB 1.1
specification, it is fully forward and backward compatible with
current USB systems.
# If your computer’s USB controller is only USB1.1 you can only
achieve a 4X maximum CD writing speed.
# If you do not have a USB2.0 port, you may install an optional
USB2.0 adapter or controller (see optional accessories section
on page 13) to your computer to achieve the maximum DVD and
CD writing speed.
USB interface cable installation
Attach the USB 2.0 interface cable to the computer connector (C2, figure
1 on Page 6) at the back of the DVD DigiCopier firm and securely – you
should not be able to disconnect the cable without pressing the release
notch.
