Appendix B: Setting up the Hub on

Windows XP

For connecting the 4-Port PoweredUSB Hub to a PC running the Windows XP operating system, keep in mind:

1.Microsoft XP Service Pack 1 or higher must be installed.

2.When connecting the Hub for the first time, it is important to perform the enumeration correctly. A Microsoft XP Service Pack issue does not enumerate and recognize a Hub when no devices are attached to it. To correctly enumerate the 4-Port PoweredUSB Hub, attach a peripheral whose drivers are included in Windows XP, such as a USB mouse, prior to enumerating the Hub. To accomplish this:

a.Connect a USB mouse to one of the lower, standard USB, Hub ports.

b.Connect the power cord to the Hub.

c.With the PC powered up, connect the host control cable from the Hub to a USB port on the PC. Doing so displays the Found new hardware dialog, indicating that the PC is searching for drivers for the Hub.

d.When the PC completes the driver search, it displays the Found new hardware dialog, in search of a driver for the mouse. If required, click Next in all screens of the wizard to complete the driver selection for the mouse.

At this point, you should be able to plug in and install a USB device provided you have also installed its drivers, or have them available for installation.
