<p dir="auto">Problem:<br />
I recently bought several new ATOM ECHO S3R.<br />
When I plug these to my USB port, I dont see a COM port appearing in my Win11 Device list. As a result I can also not connect from ESPHome to the device.</p>
<p dir="auto">I tried to install drivers from this site <a href="https://ftdichip.com/drivers/vcp-drivers/" target="_blank" rel="noopener noreferrer nofollow ugc">https://ftdichip.com/drivers/vcp-drivers/</a><br />
but that did not help.</p>
<p dir="auto">Any tips what I can do to communicate with my new ATOM S3R modules?</p>
<p dir="auto">Thanks for tips!</p>
<p dir="auto">Regards,<br />
Jules</p>
