The issues occurs on every kernel after 1302bac33d9e88cd43e482191a806998f3ed43cc commit. Before the commit, this touchpad device was detected as PS/2 mouse and "cat /dev/input/mice" shows data when the touchpad is used. After the commit, there are no events from the touchpad in /dev/input/mice or /dev/input/mouseX files anymore. According to drivers/input/mouse/alps.c source file, all devices with signatures "ec[0] == 0x88 && ec[1] == 0x08" are treated as "Rushmore touchpads". This touchpad has E7 signature of "73-03-0A" and EC signature of "88-08-22", and it looks like that V5 protocol (not "Rushmore") should be used here. If V5 protocol is forced to use for this device then everything works fine. The patch is trivial, but I'm not sure how to properly separate "Rushmore" and "V5" devices. Are there any datasheets or experts to help me with it? Thanks. -- Vasily Titskiy -- 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
