I have multiple logitech / logi hardware items accumulated over the years, I often find myself using an older device for a specific purpose (the usable lifetime of the range is incredible). The only issue I have is that I have to install and run three sets of control software to cover all the items I use Tthere is a " Not Yet Supported " tag applied to some items in later control software but I have never seen any of these items become supported - to cover user's needs properly each new control software must support all previous hardware
