No problem. In what is perhaps a bit of serendipitous timing, I also just came across this Android app which aims to make an Android device plugged into a PC via USB look like a standard keyboard & mouse - although it looks like your device needs to be rooted. If Simon doesn't work out for you (I see the Windows version hasn't been updated in over a decade, and even the Linux version has only seen sporadic activity), then perhaps this app in combination with the apps you mentioned in your OP could suffice for your needs (assuming you have an Android device since you specifically called out a couple of apps for it).
