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

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")

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.

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()

i found a fix!! first download this chrome extension then click the extension, and set the user-agent to "Chrome on Mac"
second change this line in your code
driver = webdriver.Chrome(resource_path("C:\\webdriver\\chromedriver.exe")) # to open the chromebrowser
driver.get("https://web.whatsapp.com")
to:
driver = webdriver.Chrome(executable_path=r'C:\webdriver\chromedriver.exe') # to open the chromebrowser
driver.get("https://web.whatsapp.com")
also open cmd and type:
pip install pywin32

The error is probably because you have used parenthesis in the resource_path variable. The code should be as following:
driver = webdriver.Chrome(resource_path="C:\webdriver\chromedriver.exe") # to open the chromebrowser
driver.get("https://web.whatsapp.com")
if still there is any problem you can try keeping the web driver in the same folder as the python file.

check your device list to see if there is any usb devices doesn't work.
I solved this after My laptop have been enabled bluetooth and cam devices.

The error
[15292:18896:0820/144926.111:ERROR:device_event_log_impl.cc(214)] [14:49:26.110] USB: usb_device_handle_win.cc:1048 Failed to read descriptor from node connection: A device attached to the system is not functioning. (0x1F)
disappeared after downloading and using the required web driver version for my chrome version I have installed. See https://chromedriver.chromium.org/downloads

options.add_experimental_option("excludeSwitches", ["enable-logging"]) did the trick for me without having to install pywin32.
Solution 9:[9]
I have tried many methods, but none has worked for me.
All I can do is delay the automatic exit of the Chrome browser with time modue.
from selenium import webdriver
import chromedriver_binary # Adds chromedriver binary to path
import time
options = webdriver.ChromeOptions()
options.add_argument("start-maximized")
driver = webdriver.Chrome(options=options)
driver.get('https://www.google.com/')
time.sleep(3600) # let the browser die after 1 hour

I am a member of GrapeCity’s Technical Engagement team supporting SpreadJS. I have a few questions so that I can look into what you are reporting:
- SpreadJS does not have a SetStyle event, since this can check and confirm here what SpreadJS Event you are using?
- I see you mention when you hit undo, can you confirm if this is the undo button in the Designer Component's ribbon?
- How are you setting the style of a cell?
- Please share a code snippet or sample app that shows the event behavior you are reporting.
Thank you, Mackenzie Albitz
