About USB Drives
Device Performance
USB (Universal Serial Bus) devices such as your new HP CD Writer Music
are so easy to disconnect and reconnect that you may want to use other
devices of this type. The information below can help you maintain the
CD-Writer’s performance when other USB devices are connected to your
computer.
Fast USB devices connected to your computer (such as the CD Writer
Music, scanners, printers and speakers) work well as long as they are used
one at a time. However, there is a drastic reduction in performance when
two or more of these devices are used simultaneously.
Typically, slow USB devices connected to your computer (such as mice,
keyboards, and joysticks) do not decrease the performance of other slow
USB devices. They can, however, affect the performance of fast devices
when a slow and a fast device are used simultaneously.
Using the Right Cable
The USB cable shipped with the CD Writer Music is a high-quality cable.
Do not replace it with other cables or use cable extenders. Using lower
quality cables could adversely affect drive performance.
Choosing a Hub
A hub allows you to connect multiple USB devices to your computer. To
operate properly, the CD Writer Music requires a self-powered (also
known as active) hub. This type of hub ensures that all the devices on the
hub receive the necessary power.
