Oh well, at least now I know my way around an URB :-) I found the series of patches, although I have yet to test them (and yet to build a kernel for real...), I didn't see anything dealing with the DualShock 4's touchpad in them. If the touchpad is indeed not supported yet, I still have a problem : I have no idea how to report the touchpad's data to the userspace. For now, I'm reporting the data as 4 axis (for visual feedback), but it is obviously not a solution. If I report it as a mouse, I'm losing the second touch point capability. If I report it as touch events, what I reverse-engineered so far from the protocol doesn't provide absolute coordinates for the x-axis, which seems necessary for touch events. Besides, I don't think most games will notice touch events. If the touchpad is correctly supported, well I guess it's not a problem anymore :-) I'll have to test the patches to be sure, but it might take a while for me to get the kernel rolling (I'm currently on the standard, comfy Debian testing 3.12 kernel)...
