After USB bus driver ftdibus.inf has been in-
stalled, Windows will begin installation of virtual
port driver, which enables FTR970-PRO to look
like regular serial port, for example COM3.
Finally one must fi gure out on which COM-port
the device was attached. Open Control Panel/
Hardware/Device Manager. Open ports from the
device tree, and there should be USB Serial Port
in some of the COM ports.
Repeat this procedure for other driver (usb
serial port). And fi nally check from device
manager in which com port device was
detached.
