Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39) {Unable to Load Device Driver} %hs device driver could not be loaded. Error Status was 0x%x

A yellow exclamation point next to a device in Device Manager means that Windows has identified a problem of some kind with that device is detected but not installed.

There are several causes of Code 39 errors:

· A required device driver is missing.

· A required binary file is corrupted.

· There is a problem with the file I/O process.

· A driver that is referencing an entry point in another binary file is unable to load.

I recommend you to uninstall and reinstall the latest drives from the manufactures’ website and check if it helps.

Refer to the steps from the following Microsoft article.
