I was using this prior to the windows update, and after the update installed it only works as a default keyboard unit. The razer Synapse no longer sees the unit, but the mouse hex is still visible. If I load the Nostromo default devices, it said no unit attached. but I can see it under the system devices. So basically windows 10 sees it, but the Synapse system no longer sees the unit. Tried uninstalling ect no change. So I can use the unit as a keyboard but no longer access the programable part of the Nostromo.
