Troubleshooting

1.I plugged a device or other hub into my hub and it doesn’t work.

First, verify that all of your cabling is connected properly. See page 6 for help. Next, verify that you are using an operating system that supports USB. Some versions of Windows 95, Windows NT and a number of Unix-based operating sys- tems do not support USB.

Some devices require more power than the hub can supply in bus-powered mode. If a device does- n’t work and you hub is in bus-powered mode, plug in the AC adapter.

If you are connecting a device into your hub via a serial-to-USB or parallel-to-USB converter, make sure that the device does not require any more than 500mA of power. 500mA is the maximum amount of power that a USB port can supply. Any device that needs more than 500mA of power can- not be accessed through a USB port.

2.The computer doesn’t recognize the hub or any other USB device.

The operating system has to support USB. Windows 95 OSR2, Windows 98, and MacOS 8.1 or higher support USB.

Also, the USB ports on your PC may be disabled in the BIOS. Use the BIOS menu to enable them.
