PC or OS does not
support USB 2.0.
The CS1782 has a built-in USB 2.0 hub,
so will not support PCs or OS that do not
support USB 2.0.
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.
