In few days I should recieve the Stick from bitshopper.de.
Idea is to use it in one of the blackarrow X1's usb (eventually undervolted), and I'm not a linux expert. 
Cgminer version is 4.4.2 and the task is controlled by bamc (black arrow manager software) under debian, I don't know if is a good idea to upgrade cgminer 'cause the integration with bamc.
Should I simply go to install bfg to control only GekkoSience miner and let cgminer do only present task with the minion
