Cannot configure port, something went wrong.

[mkaatman]

I have tried several USB ports and when I refresh the port checker it sees the port, but upon hitting start I always get this error. (Sonoff dongle)

Cannot configure port, something went wrong. Original message: OSError(22, 'The parameter is incorrect.', None, 87

I found a relevant stackoverflow question but no answer.

Edit: Second windows computer worked.

It seems to me that on the first computer you choose the wrong COM. For example virtual or embedded.
This error is given by pySerial.
Can you verify that the correct COM port is selected, for example, using the device manager?

You are correct. I noticed it was showing up as COM3 and after I installed the CP210x driver it works. ty!
