Kit Operation
In
Figure 3-3
, the Device Manager window identifies the WICED USB Serial COM port as COMXX.
The assigned port number varies between systems. If the device displays two WICED USB Serial
Ports (WICED USB Serial port and WICED USB JTAG Port) instead of one, then follow the link men-
tioned in this post.

3.3.2
Troubleshooting
If an error occurred during the automatic driver installation process, the driver may be manually
installed from the following directory:
<WICED-SDK>\Drivers\Windows\wiced_uart.
If the CYW954907AEVAL1F EVK does not appear in the Device Manager, verify that the +3V3 LED
is turned ON and check the USB cable.
3.3.3
External Power Supply
The CYW954907AEVAL1F EVK can be supplied using an external power supply (5V-12V, 2A), using
a 2.5 mm DC Jack with center pin positive. When using external power supply and also connecting a
USB cable (for programming/debugging or USB-UART), the voltage on the external power supply
should be greater than that of the USB supply, if not the kit will be actually sourcing its power from
USB rather than the external power supply.
