| Driver signature issue in WIN 7, when some Win7 systems install drivers after 18 years, the device manager displays a yellow exclamation mark and prompts "The digital signature of the driver required for this device cannot be verified, code 52". This is because the system lacks the system security patch supported by SHA256 signature, which can be solved by downloading and installing.
