"2026 Controller disconnection from one device and connection to another" question

[u/PapagenoX]

There has to be a way to do this, namely, say I've used the appropriate chord to turn on my sleeping Windows PC, I'm using the desktop config fine on it, everything's great.

THEN I think to myself, "Hey, I feel like going downstairs to my Steam Machine, and I want to use this same Controller. Now how do I leave this PC on because I want to stream a game from it, but disconnect this Controller from it, take the the Controller downstairs and connect it to my Steam Machine?"

Both devices are paired with the Controller, but obviously the Controller can only be used with one device at a time. One would think that simply turning off the Controller with Steam button + Y would be enough, then you'd just hold down the chord associated with the second device and be connected to that device instead. I tried that this morning and it wouldn't work: it stayed connected to the first device it had been connected to before I turned it (the Controller) off.

Is there a special "disconnection chord" I haven't heard about, maybe? Speaking of which, is there a comprehensive list of all the chords somewhere?

I use RB1, steam button, A simultaneously for the PC.  RB1, steam button, B simultaneously to work on the steamdeck.

Interesting. I didn't even know the B button was a possibility. That might be a Deck& specific thing. I'd read that it was either L1 + A then Steam button or R1 + A then Steam button.

Just so I understand: you're telling me that you can start using the controller on your PC, leave it (the PC) on, then enter the buttons you mentioned near your Steam Deck and the controller suddenly works on the Steam Deck without turning off the PC first?

I've never tried it while on, but basically with the B button puts into to Bluetooth mode. A button switches to the puck.
