I just received my new model 100. I am having the same issue that I had with my Atreus. There is something wrong with the keystrokes. I have installed the latest firmware 0.90.2+44
Sometimes there is a significant delay (1-2 seconds) between pressing the key and being typed in the computer, so there may be a word or two that I type that takes a while to appear registered on the screen. It feels like it is being buffered and then all keystrokes are sent at once.
Sometimes also the keystroke is repeated indefinitely, so I have to press other keys to stop sending it the same letter to the computerrrrrrrrrrrrrrrrrrrrrr.
I do not think it is a switch. It happens even when I am writing on a logitech keyboard (with the model 100 still plugged). This behaviour stops as soon as I unplug the model 100.
So I think that there is something going on with the PC & model 100. My guess is it has something to do with my Windows 10 machine settings. I was wondering if someone have any hints on how to debug this problem.
