Hello Arun,

Did you check if the drivers of the USB device are installed correctly on the PC?

Thanks,
Sai

PS: If using Windows, launch device manager to check if drivers are installed correctly.

hi sir,

if I connect my uart means my ports are working properly. if i connect my USB means its showing not properly initialized like that.

thanks

Hello Arun,

The USB drivers must be installed before running the PC application. Please refer the "readme.txt" file of the application.

Thanks,

Sai
