I am surprised this problem has not been resolved after such a long time.
Bought a Push 2 in the last 6 months, works OK on my Mac laptop, but my Windows PC is a lot more powerful and that's where I do all the heavy work, but the Push 2 has been a disappointment.
After using it for a while, it starts lagging, then stops responding; some other times it just becomes unresponsive (even if I am not using it, for example, if I switch to another windows to look something up); and I don't have anything heavy loaded into Ableton (using 10.1.x).
I have tried turning off the setting in Device Manager to allow windows to turn power off in the USB root host controller, but no effect. I have cleared all other USB devices from the computer, stopped all other applications, still consistently reproducible.
The LED display of the Push and the strip still work, but all other buttons do not respond. The only fix is to turn it off and back on.
Using my laptop is not a viable solution, and Mac desktops cost more than a car these days, so I may be selling it to a Mac owner if I cannot get this resolved.
