	Hello,

	have you made changes related to GPIO ? They often change meaning from a 
scanner to another. Sometimes you won't get any data until they are set up 
correctly. 
	Locate writes to registers 6c/6d and 6b for values and 6e/6f for mask in the 
USB logs you have. You'll see quite a few places where we test for the model-
>gpo_type and write to GPIO registers. Try to adapt these to match what you'll 
see in logs.

Regards,
	Stef
