I recently got a new mid-2013 Macbook Air, which seems to use a device ID that is missing from the kernel. From lsusb: Bus 001 Device 003: ID 05ac:0290 Apple, Inc. This generation of Macbook Air already has three IDs listed in the kernel (0x0291, 0x0292 and 0x0293) as WELLSPRING8, so I've added 0x0290 to that list as WELLSPRING8A. It looks like these generally come in triplets of consecutive device IDs, so it's not clear to me why there would be an extra one in this generation (and only -1 from the existing IDs which doesn't leave room for additional ISO & JIS layouts if they are numbered consecutively). With these patches the Fn key now works for me, as does the multitouch functionality of the touchpad. -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
