Failed to read descriptor from node connection: A device attached to the system is not functioning error using ChromeDriver Selenium on Windows OS

Question

I got this while running the selenium webdriver script in python I also set the path in System Environment and also tried downloading the webdriver that matches with my chrome version. And also letest version also. But I still get this error:

[8552:6856:1120/155118.770:ERROR:device_event_log_impl.cc(211)] [15:51:18.771] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)
[8552:6856:1120/155118.774:ERROR:device_event_log_impl.cc(211)] [15:51:18.774] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)
[8552:6856:1120/155118.821:ERROR:device_event_log_impl.cc(211)] [15:51:18.821] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)

I used this in my code :

driver = webdriver.Chrome(resource_path("C:\\webdriver\\chromedriver.exe"))  # to open the chromebrowser
driver.get("https://web.whatsapp.com")

Answer 1

This is a chromedriver issue that they're still working the kinks out of. I'm not entirely sure what's causing it, but the technical details seem to be detailed in Debanjan's answer.

The general solution on the internet just seems to be "ignore it", but it sure clutters up the logs a lot.

I did find a way to get it to shut up though (as well as the "DevTools" warning that pops up a lot as well).

options = webdriver.ChromeOptions()
options.add_experimental_option('excludeSwitches', ['enable-logging'])
driver = webdriver.Chrome(options=options)

You can add your other chromedriver options and switches onto that as well, in addition to pointing to your chromedriver executable if you wish.

Answer 2

This error message...

[14432:11656:1120/161059.539:ERROR:device_event_log_impl.cc(211)] [16:10:59.539] USB: usb_device_handle_win.cc:1020 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)

...implies that the ChromeDriver raised an error while in trying to initiate/spawn a new Browsing Context i.e. Chrome Browser session.

Analysis

This error occurs due to an USB device which is attached to the windows-10 system and isn't functioning properly.

This error is defined within usb_device_handle_win.cc as follows:

void UsbDeviceHandleWin::GotDescriptorFromNodeConnection(
    TransferCallback callback,
    scoped_refptr<base::RefCountedBytes> request_buffer,
    scoped_refptr<base::RefCountedBytes> original_buffer,
    Request* request_ptr,
    DWORD win32_result,
    size_t bytes_transferred) {
  std::unique_ptr<Request> request = UnlinkRequest(request_ptr);
  if (win32_result != ERROR_SUCCESS) {
    SetLastError(win32_result);
    USB_PLOG(ERROR) << "Failed to read descriptor from node connection";
    std::move(callback).Run(UsbTransferStatus::TRANSFER_ERROR, nullptr, 0);
    return;
  }

Solution

This error isn't harmful and doesn't blocks the spawning of the new Browsing Context i.e. Chrome Browser session. So you can safely ignore the error.

However in your code block you need to replace the keyword resource_path with executable_path and your effective code block will be:

webdriver.Chrome(executable_path=r'C:\webdriver\chromedriver.exe') # to open the chromebrowser 
driver.get("https://web.whatsapp.com")

Solution:

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By
from selenium.webdriver.chrome.options import Options
import time

options = Options()

options.add_experimental_option('excludeSwitches', ['enable-logging'])

driver = webdriver.Chrome(executable_path=r"D:\SW\chromedriver90\chromedriver.exe",chrome_options=options)

url = 'https://carlsagan.com/'

driver.get(url)

...

driver.quit()
