[Bug 1093237] Re: [Dell Inspiron 17R SE 7720] TouchPad detected as Generic Mouse
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.
