OK, Now I think I'm stating to understand the confusion here......

I personally dont consider i/o "Control" I certainly agree that Keyboards, Mice Joysticks, Scanners, etc offer Input, and even output but When I'm talking control, I usually am looking for an interface to my AMX Control processor......

The AMX USB Stick simply contains software from what i understand.... As I can control my PC from a Modero and I dont have the USB stick, and never did....

Crestrons new panels are Wi-Fi, as are the AMX MVP panels.

If you use a USB--->Ethernet adaptor, are you controlling the device via USB or Ethernet? I would consider that Ethernet, TCP/IP control (Orginal Fireball comes to mind)

Anyway, hope that helps on some of your queries, and sheds a bit of light on why I went on a bit of a rant there...........
