Quick Installation Guide

2.Connect the Type-A end of the cable to one of the hub’s downstream ports and the Type-B end to the USB device.

3.Check that the hub’s downstream port (green) LED is on. If this LED is off, then follow the advice in the section “Troubleshooting” to diagnose the problem.

Troubleshooting

The USB204A can be easily monitored through its indicators. You should be able to quickly resolve any problem by following the troubleshooting steps listed below. If you cannot solve the problem, contact your Accton distributor for further assistance.

General Problems

Many problems and error conditions can be cleared by first following these steps:

1.Ensure all upstream cables are properly connected and that all upstream hubs and the host PC are powered on.

2.Be sure the host PC and hub are not in suspend mode by pressing any key on the keyboard or moving the mouse.

3.Disconnect devices from the hub and reset the hub. To reset the hub, simply unplug the uplink connection and then plug it back in.

Uplink Port LED is Red

This indicates an overcurrent condition exists.

1.Disconnect devices on downstream ports 1 through 4 one at a time until the LED turns green. The last device disconnected is causing the overcurrent condition.

2.If the LED is still red with all devices removed, reset the hub by unplugging the uplink connection and plugging it back in. If the LED remains red the unit is defective and should be replaced.

A Single Downstream Port LED is Off

The port has been disabled by the host PC. An overcurrent condition may exist on the port, or the device driver identified a problem with the device and turned the port off.

1.Disconnect the device. If the port LED does not turn on, reset the hub. If the LED then turns on, you can reattach the device.

2.If the LED does not turn on after the hub reset, you may have to reboot the host PC.
