	the steps involved in adapting the backend would be to record the USB 
activity for a scan done under windows. Then process this log to extract GPIO 
settings. A new GPIO define and a corresponding entry must be defined in 
genesys_device.c . Then in genesys_gl847.c the gl847_init_gpio function may be 
have to be adapted. 
	To my opinion, there isn't much code to write but many tests to run in 
order to check that the cnages are working like expected. So this task would 
be better done by someone owning a 700F like you.
