Elantech Touchpad and Keyboard did'nt works

[miqlas]

Touchpad: ACPI\VEN_ETD&DEV_0508 Type: PS/2 compatible IRQ 12

Keyboard: ACPI\VEN_1025&DEV_0759 Type: PS/2 compatible IRQ 01 Port 0060-0060 Port 0064-0064

Everything else working correctly on my laptop (Acer Aspire M5-438TG), but the Touchpad and Keyboard.

Syslog from other OS:

ELAN touchpad found, Hardware version 4 (Firmware version 0x461f08). Touchpad ranges are X_min 0 Y_min 0 X_max 2960 Y_max 1924, CenterX 1480, CenterY 962.

Keyboard and Touchpad works with the new nightly. You can close this ticket. Thanks!

[miqlas]

Actually it is randomly happening, so please, reopen this ticket.

It is not easy to reproduce, sometimes after boot my touchpad and keyboard works, sometimes not. A reboot fixes this, but it would be nice to see a proper fix for this.

This is a Ps2 attached keyboard and trackpad in a laptop. The device reported through DSDT. May it be a problem in the ACPI? I never had any problem like this in other OS.

Haiku is not able to reset the ps2:

hrev48425 chaged the ps/2 init to fix a similar problem. Does it helps?

[miqlas]

I haven't seen this problem some revisions ago, so i think it is fixed. Thank you guys!

[miqlas]

Hi Guys!

Please, reopen this ticket, as this bug happening again. I cannot give any extra details, but the syslog is the same as before.

I have Yubikey in my USB port, it report itself as an usb keyboard and i have an usb mouse also. Can it make any problem like this? I dubt, but who knows?

[siarzhuk]

For years I was default assignee for this PS2 stuff. Neither fixes nor improvements - I should be fired away. ;-)

[miqlas]

Tested now, it works properly. You can close it, siarzhuk. Thank you, and no, we don't fire you :)

[pulkomandy]

Are you sure it's really fixed this time? :)

[miqlas]

I think this is not ELAN related, i've just seen it on Thinkpad X200 too.

I finally am able to at least book Haiku in safe mode now on my Chromebook C720P thanks to Coolstar's custom bios. There are some USB bugs that prevent Windows from loading too, apparently. Here is the guide I used to update my bios, it has information on the Elan trackpad drivers too. ​https://docs.google.com/document/d/1yfIjx-fJXPvs6EwSdjRnokJ6ktNxeExZmVin9mamVZU/edit?pref=2&pli=1
