This article was previously published under Q175489 SYMPTOMS
When you connect a serial pointing device to your Windows NT-based
computer, Windows NT may not detect the pointing device.
CAUSE
This behavior can occur if a serial pointing device is already connected
to a serial (COM) port. Windows NT detects only one serial pointing
device.
MORE INFORMATION
The second pointing device is not detected because the IntelliPoint and
Windows NT drivers search for only a single serial pointing device
connected to the computer. When a serial pointing device is detected, the
IntelliPoint and Windows NT drivers stop searching the serial (COM) ports
for additional pointing devices.
