Hi,I am also seeing the same issue.
"Sending 3020: receiveData timeout after 400ms"I'm using an Asus 302 Flip Chromebook, ans an Arduino UNO R3.
The problem started after Chrome OS upgraded to version 74.
Hmmm... I'm on an (recent build) Acer, running version 73.0.3683.114. The UNO (a clone) I can flash, but the Nano (also a clone) I cannot. Chrome offers update towards next version; 74?
