A. What type of mouse are you using? If it’s an RS-232 serial mouse, see steps B and
D. If it’s a PS/2 mouse (either a regular type or a wheel mouse), see steps C and D.
If it’s a Microsoft BallPoint mouse, see step D. At the time of this writing, the
ServSwitch Jr. does not support other types of mice.
B. RS-232 serial mouse: Make sure that you’re using the right COM port, and that
the mouse driver is looking for the correct port.
C. PS/2 or PS/2 wheel mouse: To recognize the mouse, the CPU must be directly
connected to it, or indirectly connected to it through the Switch, at boot-up time.
Make sure that all cables are properly seated and that the Switch is receiving power
from another computer, then reboot the CPU.
D. Your mouse driver might be old or incompatible with your mouse. Try the latest
version of the Microsoft mouse driver.

doesn’t support it.
B. If your mouse is a Microsoft BallPoint, you need the latest version of the
Microsoft mouse driver.
C. If your mouse is a Logitech mouse, the Switch supports the two-button models
but not the three-button models.

Cabling might have been disturbed during mouse movement. Issue the Send Null
Byte command (see Section 4.3.5) one, two, or three times to get the mouse back
in sync. You need the latest version of the Microsoft mouse driver to stop this from
happening.
