Zadig killed my wireless keyboard

[Megapsychotron]

A couple years ago, I made my own Bluetooth Passthrough adapter, and it worked fine. I haven't played a Wii game in almost a year, so I fired up Dolphin (always kept up to date), and the adapter would not sync to my Wii controller. No big deal I thought, probably need to update the driver. I ran Zadig as the instructions were written. But it didn't work. Then I discovered the letters on my Logitech K400 keyboard weren't responding (trackpad still was). I uninstalled the bluetooth adaptor, uninstalled the Logitech keyboard, tried to have Windows install its driver. None of it worked. Thankfully, a System Restore point from a couple days ago saved my situation.

I guess I'm going back to a Dolphin bar...

So I connected the Wii controller using Emulate the Wii's Bluetooth adapter, and now it works. I guess I must have missed some Progress Report regarding this. How does this compare to Bluetooth Passthrough? Any major advantage to Passthrough anymore?

You've switched to the older implementation that was the only thing available before passthrough was implemented. You're much more likely to experience issues with Wiimote speaker audio, third party controllers refusing to connect, and the controls for games feeling janky this way, so if you've got hardware that supports passthrough, it's better to use passthrough.

As for your original problem, my initial guess is that you'd accidentally told Zadig to be the driver for hardware that wasn't specifically the adapter you use for passthrough, and therefore it got mistakenly used instead of the real driver, so you could probably solve it my changing the setting that controls that.
