Unable to Pair Logitech K380 Try Connecting Your Device Again

Logitech Unifying devices not able to pair. List does not display any devices. Is there a way to wipe the list of paired devices through the file system or registry?

I am attaching the EngineLog file from the Unifying receiver to see if anyone can help.

So i finally resolved this issue. I went through and 'cleaned' out every single sign of the Logitech keyboard. mouse and unifying controller I could find on the system (including registry keys).

Then I went in as the local admin user and installed a FRESH unifying controller with NO DEVICES associated.

I then proceeded to associate the devices one by one.

Sadly, Logitech Support was of no help whatsoever.
