4.2 Drivers for the USB-EA emulator
If the USB drivers for the USB-EA dongle do not install automatically on your PC, then
download drivers for the FT245R part for your operating system from the following website:
http://www.ftdichip.com/Drivers/D2XX.htm
When the drivers are installed and USB-EA dongle is connected to the PC, it will appear as an extra
COM port under the Device Manager window – see the figure below.
Note: The older versions of the Keil tools only work with COM port numbers of COM8 or lower.
If your PC allocates a COM port number of COM9 or higher, then you will need to change the COM
port to a lower number.
To do this, right-click your mouse on the USB-EA entry in the Device Manager window and select
Properties.
