You think they are too many cables on your devlight ?

yes mee too :

Yes it is possible to develop applications with only one cable :

To program the apf, we need tree cables to

* Power the kit (AC/DC bloc)
* control the system (RS232)
* download files fast (Ethernet)

But it is possible to use only USB to :

* *Power the kit* : USB protocol can provide up to 500mA
* *control the system* : tty console can be emulate over USB
* *download files fast* : with USB tty console can be more fast than standard RS232 then, big files can transit trough it.
