Subject: i8042_init: PS/2 mouse not detected with ACPIPnP/PnPBIOS
Date: Wed, 7 Oct 2020 23:18:41 +0200 [thread overview]
Message-ID: <1a69c5bc-ccc4-68db-7871-af05a70052c9@molgen.mpg.de> (raw)
Dear Linux folks,
On the Asus F2A85-M PRO Linux 5.9-rc8 (and previous versions) does not
recognize a plugged in PS/2 mouse using the Plug & Play method. The PS/2
keyboard is detected fine, and using `i8042.nopnp`, the PS/2 mouse also
works.

But, the DSDT includes the “mouse device”. From
acpidump > dump.bin; acpixtract dump.bin; iasl -d *dat; more dsdt.dsl
we get
Device (PS2M)
{
Name (_HID, EisaId ("PNP0F03") /* Microsoft
PS/2-style Mouse */) // _HID: Hardware ID
Name (_CID, EisaId ("PNP0F13") /* PS/2 Mouse */)
// _CID: Compatible ID
Method (_STA, 0, NotSerialized) // _STA: Status
{
If ((IOST & 0x4000))
{
Return (0x0F)
}
Else
{
Return (Zero)
}
}
and the identifiers PNP0F03 and PNP0F13 are both listed in the array
`pnp_aux_devids[]`. But adding print statements to
`i8042_pnp_aux_probe()`, I do not see them, so the function does not
seem to be called.
Hints for further debugging are much appreciated.
Kind regards,
Paul
