i havbe an esp32 c3 i bought and after flashing a sketch to it and resetting afterwards it is only detected as usb jtag and not a serial (COM) device i tried holding boot while plugging in but no luck

Hi @LucaCraft89, are you using the ESP32-C3-LCDkit board? If so, it is indeed only detected as a USB JTAG. Because the USB port is directly connected to the chip as below.

Hi @Lzw655 i'm not and before i got the jtag behavior i was able to get the serial port

Please provide the detailed development board model and version you are currently using.

I got it on AliExpress

Well, it's not an official ESP board. Looks like this board directly connects the USB port with the ESP chip as same as the picture I showed before. If so, it should not be detected as a serial (COM) device anyhow.

Please check its schematic or provide it here and I'll check it.

According to this schematic, the USB port is directly connected to the ESP chip and it should always be detected as a USB JTAG device.

@LucaCraft89 Hi, for the USB-Serial-JTAG controller in ESP32-C3, which has two interfaces, one is a USB serial interface, and the other is a USB JTAG interface. Two new devices should be detected as below:

If you can not find the serial (COM) device, please re-install the driver using tools like Zadig, choose interface 0, then choose usbser or USB CDC driver

Fact is i don't seee the second one
