Does the keyboard/mouse get properly discovered if you unplug and replug the receiver? Linus reported that sometimes this is the case for him as well. Quoting my response to him two days ago: === we have had such reports before, but commit a9dd22b730 (and subsequent revert of workaround fone by 59626408) was supposed to fix exactly that. Any idea when this started happening to you? What if you revert back to the 59626408 workaround (i.e. revert a9dd22b730 and 8af6c0883)? I have a couple of unifying receivers myself, but was never able to see this problem ... so it's either rather timing sensitive, or device-specific. === > > In case the model matters: > My mouse: logitech M705 > Keyboard: logitech K270 > The logitech unifying receiver came with one of them.
