Just a couple clarifications: 1* Not all chips have subclients, in fact most haven't, only Winbond chips and Asus clones have. 2* In our current implementation, subclients are registered only to prevent other drivers to use them. They are not accessed by their address (the same functions are available from the main address). -- Jean Delvare
