seconds; then turn the PCs on.
Wrong type of
mouse or adapter
The switch will only work with
a PS/2 mouse. A serial mouse
cannot be converted to a PS/2
mouse by using a serial to PS/2
adapter. One exception is a
combo-mouse which is specifi-
cally designed for both applica-
tions. In this case, ensure that
the mouse is set up for PS/2
mode and is being used with
the adapter originally provided.
Unsupported or
incorrect mouse
driver
Each PC needs to be using
the mouse driver correlating to
the mouse connected to the
console port.
Some newer mice (with extra
buttons and wheels) have
unique drivers that may not be
supported.Try a regular mouse
with a generic mouse driver
(like the one that comes with
the operating system).

, have trouble working with a switch when their mouse and
keyboard ports are used simultaneously.To avoid this problem, only
connect the mouse port or the keyboard port to the Switch. If you
connect the mouse port, you will need to use the notebook’s
keyboard when the notebook is the active computer. These
switches are designed to work with PS/2 keyboards. Older XT
(84 key) and AT keyboards will not work.
