As if it wasn't bad enough that they want me to use a random internet service to add a keyboard to a usb wifi receiver, they have the balls to put this for Firefox users. I clicked out of pure curiosity, as I'm not even remotely interested in involving a corporate internet service in getting my keyboard connected to my computer. This is the message you get now on Logi Options software if you have a Unifying Receiver:

EDIT: some people on the thread have brought up that the error message being displayed for Firefox users is due to the WebUSB API not being implemented by Firefox due to security concerns. This still does not justify having to use a web app to plug peripherals to a PC.
The G915 uses micro USB from memory.
I'm happy with the logi peripherals that I own, but I don't use windows or care for most of the extra features they come with.
Ah, my bad, I've never owned or looked into a G915 but just looked for a picture to make sure it was type c.
Logi must be sitting on stockpiles of mini USB connectors lol. Was so surprised that they were using them on modern stuff.
Even the superlight uses mini, it's such a pain having everything else on my desk be type-c and my mouse requires an antiquated standard.
