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. 
thx for the update 
Hi @joseilton ,
Is your issue the same as the one in this thread Error with Chrome version 88? If you have a solution can you help them?
