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 request_buffer,
    scoped_refptr original_buffer,
    Request* request_ptr,
    DWORD win32_result,
    size_t bytes_transferred) {
  std::unique_ptr 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")
