DisplayLink USB driver stopped loading

[JerryB]

Hello,

This laptop computer has been using the DisplayLink drivers for quite a while to support two external monitors. However a few days ago, the external monitors stopped working. The USB hub functionality still works, but the external displays do not.

The device manager indicates the two DisplayLink USB Devices in Device Manager's Display Adapters section both show the yellow warning triangle and the property dialog says the drivers cannot be loaded with a Code 31.

I have tried numerous unloading, computer restart and reloading the DisplayLink installers (both the latest Versions 9 and 10 and a couple of previous versions) without success. I also disabled the Windows defender real-time protections during the DisplayLink install. The DisplayLink installer does not complain about any problems during the install, but the problem indication persists in device manager.

I have attached the support file created for a DisplayLink V9.2 M3 install.

I would appreciate some help getting the external monitors working again.

Thank you.
Jerry
