Maybe they could release it as a Chrome extension/app? They have the Chrome OS recovery drive tool that lets you make a USB drive. So I don’t see why they couldn’t have something that could update the controller via USB cable. But I also am not a coder/dev and lack knowledge of what can or can’t be done. It would be good if they can since they really wanted Chromebook users to game via Stadia anyway. Otherwise the Stadia app for Android and iOS was able to get updates going on the controller before anyway and could be used (if they wanted). And if any of the ideas above don’t work, then maybe it could be made to work in WINE?

Just from a web developers perspective: providing the tool online without install is possible with WebSerial or WebUSB
