Hello! I've got a third-generation MacBook and the Fn-Key is not working, althought CONFIG_USB_HIDINPUT_POWERBOOK is set to y. I checked drivers/hid/usbhid/hid-quirks.c and found, that the device_id of my keyboard isn't specified there. I changed #define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x021b to #define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x022a and everyhting is working fine. I had the same issue on my desktop, where I have an new apple desktop keyboard. Here I had to change to #define USB_DEVICE_ID_APPLE_GEYSER4_ISO 0x0221 and also everything was working. Maybe this should be added for the next release. Regards Tobias
