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
