Error: Unable to detect the device in ESP Lanchpad

[varshilgandhi]

Hi, Varshil here,
I am trying to flash the light bulb example code in ESP-C3 Board.
When I connect the Dev kit of ESP-C3 with the Laptop and then click on the connect button of ESP Launchpad.
When I click on the connect button it gives me unable to detect the device.
BUT I already connect board with system and for cross checking I type this command in terminal:
ls /dev/tty*
and after run above code I can see my board is connected.
But ESP Launchpad shows that it is unable to detect.

@varshilgandhi, you mentioned connecting the DevKit through the CLI. Have you tried disconnecting and then connecting it through ESPLaunchpad? If you continue to experience issues after trying this, kindly share your system details, including the operating system and browser you are using. This information will aid us in identifying and resolving any potential compatibility issues. Thank you!

@Bryanmusika, from the system configuration that you had mentioned, it seems like you may be facing this issue (Problem with most current [11.2.0.167] CP210X driver). Please try downgrading the drivers upto the version which was mentioned in that issue and let us know if that resolves the issue. Apologies for any inconvenience, and we are actively looking into this problem.

@hramrach, I think it might be a read/write permission issue on Linux. Could you try this once ?

[hramrach]

yes, it's a permission problem.

It can be fixed with an udev file:

cat /etc/udev/rules.d/espressif.rules
#303a:1001
SUBSYSTEM=="tty", ATTRS{idProduct}=="1001", ATTRS{idVendor}=="303a", OWNER="hramrach"

Note: some other WebUSB flashing tools specifically report this problem which makes it easy to diagnose.

On the other hand, ESP Launchpad provides a generic 'something failed' message.

@hramrach, Thanks for you feedback!

You mentioned that some WebUSB flashing tools provide more specific error messages. Could you please share a list of those tools? It would be really helpful for improving the error handling in ESP-Launchpad.
