Problem
Cause
Solution
USB device is attached to client
extender USB port but the client
extender device LED is off.
• The USB device must have the
appropriate driver installed on the
computer operating system.
• Install the required USB device driver on
the computer operating system prior to
attaching the USB device to the client extender.
Please see your USB device manufacturer’s
website for details.
• Consult your USB device documentation
and power your USB device with the additional,
USB device manufacturer supplied, power supply
(if available).
Device LED is orange and host/
client extenders are no longer
functioning.
• Overcurrent condition has occurred
because USB device draws more
power than can be supplied per USB
specification (500mA).
• Power cycle the client extender.
LED Host and LINK LEDs on
host and client extenders blink
intermittently.
• Firmware mismatch between the host
and client extender.
• Use a different host/client extender pair
which have the same firmware revision.
• Upgrade the host and client extender firmware,
contact technical support for assistance.
