PS7, Line 44: 	SSFC_TOUCHSCREEN_ELAN9008,
> Yes, ELAN9008 and ELAN0001 both are at same slave address (0x10)

* Could you have them with different i2c slave address by either FW or HW strap pin?
* Looks like ELAN0001 is in generic i2c driver but ELAN9008 is in hid over i2c so could you confirm kernel can not probe them correct and disable non-existed one?
