What do you mean by "support"? 11-RELEASE "mouse with tap detection" - like? That is what I am trying to do now. If something of what I proposed helps, = I'll try to add quirk to kernel driver to enable tap support automatically. If n= ot, we can dump PS/2 bytestream to find out "what is up?" If you mean full-blown absolute mode driver, than answer is "most probably = no". I have to have a physical access to laptop to write and debug such a driver. Really things are worse as there are 9! different versions of ALPS PS/2 touchpad protocol and it is not clear which ones are major or minor. > or FreeBSD purposefully phase such devices out. Such devices are phased out by history rather than by FreeBSD. Their worst property is that they are not supported good enough by Windows. MS precision touchpad specs includes only USB and I2C devices, not PS/2, that is why new laptops do not contain PS/2 touchpads. That means that chances that someone= who is motivated enough to write an absolute-mode driver for such a rare device will get a sample of it are relatively low. But, that does not mean that FreeBSD wants to let it rot. --=20 You are receiving this mail because: You are the assignee for the bug.=
