Checking the Installation
1. On the local and remote extenders, check that the Power, Status, Link and Host LEDs are on.
If the Host or Link LEDs are permanently off, then the cabling between the local and remote
extenders may not be installed properly or is defective.
2. For Windows users (XP, 7, 8), open Device Manager to confirm that the DIGI-USB2-4H has installed
correctly. Expand the entry for Universal Serial Bus controllers by clicking the “+” sign. If the
DIGI-USB2-4H has been installed correctly, you should find it listed as a “Generic USB Hub”.
To open Device Manager in Windows XP:
Right click “My Computer” then select: Properties >> Hardware tab >> Device Manager
To open Device Manager in Windows 7:
Open the Start menu, right click on “Computer” then select: Manage >> Device Manager
To open Device Manager in Windows 8, 8.1 or 10:
Right click the Start Menu and then select: Device Manager
3. For OS X users, open the System Profiler to confirm that the DIGI-USB2-4H has installed correctly.
In the left hand column under Hardware, select “USB” and inspect the right hand panel.
If the DIGI-USB2-4H has been installed correctly, you should find it listed as a “Hub” under the
USB High-Speed Bus/USB Bus.
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.
