I’m having an issue with my ESP32 C3 – the device is not being detected properly in Device Manager. When I connect it to my computer, under “Universal Serial Bus Controllers,” I don’t see “USB JTAG/serial debug unit.” Instead, I only see other USB devices like “USB Root Hub” and “Composite USB Device.”
I found a suggestion on this forum to check if “USB JTAG/serial debug unit” appears under “Universal Serial Bus Devices” in Device Manager. If it does, the next step is to right-click and update the driver. Unfortunately, this device doesn’t appear for me, even though I’ve tried using different USB ports (2.0, 3.0, 3.1) and different cables.
Additionally, I tried pressing the RST and Boot buttons to enter programming mode, but that didn’t work either.
I’m also able to upload code via Arduino Cloud, but I cannot do it locally. When I try to upload code locally, I get the error: “Failed uploading: uploading error: exit status 1.”
Has anyone encountered a similar issue? What drivers should I install, or what other steps can I take to get my ESP32 C3 detected properly?
When you encounter the above two situations, you can try to put XIAO into BootLoader mode, which can solve most of the problems of unrecognized devices and failed uploads. The specific method is:
Long press the “BOOT BUTTON”.
Connect the Seeed Studio XIAO ESP32C3 to your computer while holding the BOOT BUTTON.
I know about that; I held this button for ten seconds and for about a minute, but nothing changed.

A serial exception error occurred: Cannot configure port, something went wrong. Original message: PermissionError(13, ‘Urządzenie dołączone do komputera nie działa.’, None, 31)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
