Hey @noa1,

can you try using another USB cable? And make sure you are using Google Chrome.

Let me know if this helped,

Hi,

I’m having the same problem, using Chrome on Ubuntu, tried all USB ports and several cables, always same result:

Failed to execute ‘open’ on ‘SerialPort’: Failed to open serial port.

Is there an aternative way to restore the firmware?

More info from the Chrome console:

I’ve changed to use Edge browser on a Windows PC and now I get this error:
The device has been lost

Here I can see that the USB device in Windows keeps appearing and dissapearing all the time, every 3 seconds or so. So I can select the device in the browser Serial Port selector, but then the device disconnects…

Not sure how I can solve this issue…
