ERRATIC MOUSE POINTER: The device driver defaults to query an attached device to
find out whether it is a mouse or modem, consistent with native COM port operation. Some
RS232 peripherals constantly send short packets of data, causing the host system to “think” a
mouse or modem has been attached. These short packets will interfere with normal mouse
operation causing the pointer to jump around the screen. If this happens, disconnect the
RS232 device and
uncheck the Serial Enumerator
option, also found on the Advanced driver
options screen in Figure 2.13.
COM PORT IN USE: Windows keeps track of all COM port assignments. If multiple FTDI
products have been connected to a single system, the COM port number will increase, even if
the other devices are not attached. If the higher COM port assignments are not acceptable for
the application, known unused COM port numbers should be uninstalled according to the
FTDI installation guide: http://ftdichip.com/Documents/InstallGuides.htm.
