Hi there,
I have an original Razer Kishi v1 controller. It’s worked with some games in the past. I recently started Steamlink on it playing RE4 and it seems to work for literally about half a second. The blue light on the right blinks on and then off. In that split second I can control the game how it’s supposed to be controlled and then suddenly it dies.
I’ve updated the firmware, reset my phone, updated Steam Link, done everything I can. It just seems like this controller doesn’t want to bother working for many applications. In addition I’m running a Pixel 6a. The only button that seems to work consistently is the “Back” button. If you hold it down for four seconds it goes to the Steam Link edit page. That’s it.
