3.4 Checking the Installation
1. On the LEX and REX units, check that the Power, Host, and Link LEDs are on
and that the Activity LED is blinking. If the Link LED is permanently off, then the
cabling between the LEX and REX unit is not installed properly or is defective.
2. For Windows users (2000, XP, Vista, Windows 7), open Device Manager to
confirm that the extender has installed correctly. Expand the entry for Universal
Serial Bus controllers by clicking the + sign. If the extender has been installed
correctly, you should find it listed as a “Generic USB Hub.”
3. For Mac OS X users, open the System Profiler to confirm that the extender has
installed correctly. In the left hand column under Hardware, select “USB” and
inspect the right hand panel. If the extender has been installed correctly, you
should find it listed as a “Hub” under the USB High-Speed Bus/USB Bus.
4. If the extender is not detected correctly or fails to detect, consult Section 4,
Troubleshooting.
NOTE: To open System Profiler in OS X: Open the Finder, select Applications, then
open the Utilities folder and double click on the System Profiler icon.

Computer,” then select: Properties >> Hardware tab >> Device Manager.
