I have seen in the ESP32-C6 Technical Reference Manual that the ESP32-C6 supports UHCI.

How gets an USB port connected to the ESP32-C6 and how is it supported in the ESP IDF to connect USB devices to it?

Thanks for the feedback, this explains it.

Why didn't you approve my second topic regarding the forum search issue?

Have you tried the CDC Virtual COM Port example?

I am wondering if this virtual COM port example would also work with an ESP32-C6.
It says there that USB OTG is required, which the C6 does not have, but it has UHCI support.
Is there a way to connect an USB-Serial adapter to the ESP32-C6?

I have only ESP32-C6 left in the application selector, but if I check then "Ethernet" in the peripherals filter, then all of them disappear. https://products.espressif.com/#/product-selector?names=&filter={%22Wi-Fi%22:[%222.4%20GHz%20802.11%20b/g/n%22],%22Thread/Zigbee%22:[%22Available%22],%22Produc...

If I search for
"esp32-c6" ethernet
then the search says it ignores the "C6", but I want to have the C6 included in my search.
What is wrong?

Thanks for your response. I found in the meanwhile out, that a too low stack on another task caused the problem, even the highWatermark did not report a too low stack.

I am run after some time of operation into the problem, that my ESP32 restarts with the above mentioned error. The Modbus master code is pretty much the same as the example which is included in the ESP IDF, i just changed a few minor things. I (1911922) count_task: RAM left 123264; mb_master_hwm: 15...
