ETPS/2 Elantech Touchpad does not work at all

[grexe]

related to #15340 but that was i2c, this one is PS/2

ETPS/2 Elantech Touchpad is reported as PS/2 touchpad on Linux, so it should at least fallback to mouse mode, which is not the case, it does not work at all.

Using a Lenovo ThinkPad V510 with latest Haiku Dev nightly hrev53889.

Relevant syslog output below:

KERN: Elantech version 594F03, under developement! Using fallback.
KERN: ps2: probe_mouse Standard PS/2 mouse found
KERN: ps2: devfs_publish_device input/mouse/ps2/standard_0, status = 0x00000000

Please attach a syslog.

Well, a PS2 mouse is published, so it's strange that nothing works. Perhaps tqh would know more?

It fallbacks to standard ps2 mouse, so it should work. Not sure why that doesn't work. Maybe a hardware switch on device to enable/disable?

Is it possible that the WIP probing of the Elantech driver leaves the touchpad in non-standard mode after probling and then it doesn't work as a mouse anymore?

it works now with the latest nightly hrev53898 ! Great work, many thanks, much appreciated! So I guess the fallback is working now, but not the actual driver, because scrolling does not work yet (2-finger-gesture) and I don't see a touchpad in the input preferences, but I have a PS/2 "mouse" now:)

hmmm strangely stopped working now with same Haiku rev. Seems initialization is pretty borked (may as well be my laptop)

Yes, we have not changed anything, so it seems pretty random.

Some useful documentation I found for the Elantech driver: ​https://www.kernel.org/doc/html/latest/input/devices/elantech.html

And the last character of the version number is the hardware version - at least I think it is.

As of beta2, trackpad is still not working.
