Awhile back I decided I would just look into fixing this myself but only got as far as finding out that the code would not match my device at all. The testing was getting beyond the point of a solution. It seems like there was hope that it would magically be fixed.. I provided the information that showed the code would not match the device.. "alps: Unknown ALPS touchpad: E7=73 03 50, EC=73 02 02".. There was no way the code would match that ec sequence. This was the point where I left it as I got busy doing other things and did not have the time or desire to fix this anymore.
I have found since then that this was resolved in the commit 2013-12-26 Input: ALPS - add support for "Dolphin" devices I am not sure if the device is really considered a "Dolphin" device however I don't really care because the touchpad seems to work and has no issues that I know of or have experienced. The following snippet shows the change to now match the existing ec sequence by correctly matching the second byte. @@ -1845,11 +1975,13 @@ static int alps_identify(struct psmouse *psmouse, struct alps_data *priv) if (alps_match_table(psmouse, priv, e7, ec) == 0) { return 0; } else if (e7[0] == 0x73 && e7[1] == 0x03 && e7[2] == 0x50 && - ec[0] == 0x73 && ec[1] == 0x01) { + ec[0] == 0x73 && (ec[1] == 0x01 || ec[1] == 0x02)) { ** Changed in: linux (Ubuntu) Status: Incomplete => Fix Released -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1093237 Title: [Dell Inspiron 17R SE 7720] TouchPad detected as Generic Mouse Status in The Linux Kernel: Unknown Status in “linux” package in Ubuntu: Fix Released Bug description: Laptop is a Dell Inspiron 17R SE.
