The CS1782 has a built-in USB 2.0 hub, so
will not support PCs or OS that do not support
USB 2.0.
For OS that do not support USB 2.0,
keyboard and mouse functions can be reset
using the [F1] hotkey function. See the note
under Mouse Emulation Control on page 18.

1. Unplug the KVM cable from the com-
puter’s USB port.

remove the Unknown Device entry.

now recognize the device.
There are ghost
images on the

monitor.
The distance between the external console and the CS1782 is too
great. The maximum VGA cable distance should not exceed 20m
and, in some cases, may need to be shorter. Replace the VGA cable
with one of an appropriately short length.
