B: EV=f B: KEY=420 7000f 0 0 0 0 B: REL=3 B: ABS=1000003 The 'KEY' line looks suspicious. From what I can tell the sysfs attributes are exported as an array of longs, which is broken when a long is not the same thing for userspace and kernel. udev detects a touchpad when BTN_TOOL_FINGER (0x145) is set in capabilities/key. When reading '420 7000f 0 0 0 0' as an array of 32-bit quantities, that's not set. Cheers, Julien
