So basicly it's a USB-Port with a bit more power ?

The examples pages shows a barcodereader (these work very fine with  
standard USB and even PS/2-Keyboard) and a POS-printer. I find it a bit  
strange to power a ~50W POS-printer from a laptop. Seems like a IBM-only  
tech to me.

Is there a downside ? Does the USB-par of the port work like a normal  
USB-2.0-port ?
