Hello,

my brand new computer (amd64, Bullseye) can be suspended to ACPI Mode S3 by "acpitool -s" under Debian.

But whenever the USB mouse is moved (even a jiggle is enough) or the USB keyboard a key is hit, the computer wakes up from S3.

In Windows this behaviour can be disabled per device in the system settings:

(I'm sorry to offer screenshots only in German)

How can this wakeup behaviour by USB devices be disabled under Debian?

Thanks in advance.

Best regards,
Klaus.

Maybe the BIOS / UEFI Firmware has options for this?

Kind regards,

The solution was found by "acpitool -w".

Several of the devices were enabled at my host.

By try&error I figured out which one is my keyboard (XHC1) and which one
my mouse (PTXH).

I disabled it those by:
echo XHC1 > /proc/acpi/wakeup
echo PTXH > /proc/acpi/wakeup

...but "acpitool -W <device nr>" should also capable.

TY.
