I’m automating some tests, but when I execute the command “robot XPTO.robot” the CMD screen display the error message: “_USB: usb\_device\_handle\_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning._”

In fact, this type of error does not interrupt the test, but the log is full of dirt.

Has anyone here had this problem or know how to solve it?

Thank you n advance.

Hi, my guess is : you read and write from to an usb device that is corrupted

make a backup and test with an another one

Thank you @serici, but I’m not using any kind of USB driver.

It looks like it’s some kind of message from chromedriver. I managed to solve the problem by placing the instruction **options** after the browser’s name:

_Open Browser about:blank ${BROWSER} options=add\_experimental\_option(‘excludeSwitches’, [‘enable-logging’])_

Any way thank you very much for your assistence. 👍

Hi @joseilton ,

Is your issue the same as the one in this thread [Error with Chrome version 88](https://forum.robotframework.org/t/error-with-chrome-version-88/1233)? If you have a solution can you help them?

Dave.
