Chapter 4: Troubleshooting
Problem:
The USB device is detected as using too much power in the Operating System.
Possible Cause:
• The USB device needs more power then the Extender can support.
• The Host is not providing enough power to the Extender.
Solution:
1. Connect the Local Extender to a different USB port on the Host.
2. Connect a self-powered USB hub between the Remote Extender and the USB
device.
