Hello. I work on a Linux mint system and are a member of the dialout and plugdev group (I read somewhere that that is necessary) PlatformIO is unable to detect the boards, i tried it with the boot button pressed and unpressed and with 3 different cables, googled the problem but what i found was a…

I can’t believe it. 2 days of thinking and genarfing. And it were the cables all along. Thank you Maxgerhardt. And have a nice day.

In the CLI what does pio device list show?

pio device list,Gives nothing, a blank line

Then the computer is not recognizing the device at all. Unplug the device. Execute sudo dmesg -w in a terminal and press enter. Plug the USB cable back in again. What new lines do appear?

I checked with 3 cables and boot button pressed and not pressed, nothing. Then checked with removing usb mouse just to see if something would happen , and it does.

both boards have a display, displays picture than scans Wi-Fi and displays access points and then tries to connect to a non-available access point

and with boot button pressed display a blank screen

i also begin to think that it is hardware failure, but it is strange, 2 different boards, 2 different sellers , same failure. The only thing they got in common are the cables. Thinking of buying a new cable, the others came with appliances for charging purposes, maybe they don’t have data?. Maxgerh…

Does it work on another computer?

If not, I suspect hardware failure.

Does the board seem to have power when plugged in? (Power LEDs on or something)

If you have a multimeter, measure some voltage rails / pins, like 3V3, 5V, etc.
