برطرف کردن مشکل device manager error code 39 در USB Controller
What will you do if all the USB ports of your Desktop/Notebooks stopped working all of the sudden? At first, we might think the issue is with USB port and needs to replace the corresponding hardware device to solve the issue.
Code 39 is a common error message for USB controllers. Uninstalling and reinstalling USB drivers may not solve this issue. Code 39 may also show the error message “Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)”.
Code 39 error may be shown on USB devices like “Standard enhanced PCI to USB host controller” and “Standard OpenHCD USB host controller”.
I found that Code 39 errors with USB controller is shown when an invalid registry values are saved in Windows Registry. We need to check whether registry values like “UpperFilters” and “LowerFilters “ is listed under {36FC9E60-C465-11CF-8056- 444553540000} as this entries will prevent the USB devices to work properly.
