I've also tried manually updating the driver of the 'Unknown USB Device (Device Descriptor Request Failed)' - the Arduino - manually, but, I can't seem to make it work. What were the results you observed that did not match your expectations? I have tried installing the CH340 drivers (through the CH341SER.exe, or something similar) and it says that the Drivers have been sucefully pre-installed.What were the results you expected from doing that thing?.If that COM5 port is indeed your ESP8266 board (instead of it being from some other random device attached to your computer, which is also possible), then it appears everything is perfectly fine.Īre you experiencing some problem when using your ESP8266 board in Arduino IDE? If so, please provide a detailed explanation of the problem, including: If your ESP826 board does use the Silicon Labs CP210x USB chip then it is normal and expected that you wouldn't see it listed as a CH340 in the Windows Device manager.

Hi It appears your ESP8266 board might use a Silicon Labs CP210x USB chip instead of the WCH CH340 chip.
