Regression: touchpad and trackpoint not working (probably after July 2022)

[fatigatti]

I have a Toshiba Portege Z30 laptop, which has both a trackpoint and a touchpad. Both were (and in fact are, just tested) working fine with R1/Beta 3.

They stopped working long ago and I didn't report, because I wasn't really active in the community at the time and in fact I wasn't sure that they were working in first place.

I suspect this is related to ​https://review.haiku-os.org/c/haiku/+/5388 as pulkomandy was looking for testers then but I wasn't around.

Relevant lines in syslog are the following, printed over and over:

KERN: ps2: hot plugin of input/mouse/ps2/0
KERN: ps2: device input/mouse/ps2/0 still active, republishing...
KERN: ps2: devfs_unpublish_device input/mouse/ps2/0, status = 0x80006003
KERN: ps2_dev: reset failed: I/O error
KERN: ps2: devfs_publish_device input/mouse/ps2/0, status = 0xffffffff
