Yes - Desktop has front and rear USB.Tried wired mouse and the WiFi mouse in the back but that don't work, although both the mice light up so at least there is power at the USB's
Not sure about Keyboard, this is also WiFi, I have been able to open "Mail" using it but nothing else.
There are several round plugs at the back of the desktop but not sure what they are, coloured Green, Pink, Blue & yellow
Not sure if any of this is any help to you?
