Disable USB 3.0 trigger wakeup after sleep

Hi everybody,

My dell laptop is waking up immediately after a sleep command.
I already read some topics and the wiki, but I did not find the solution

 cat /proc/acpi/wakeup
Device  S-state   Status   Sysfs node
RP01      S4    *disabled  pci:0000:00:1c.0
PXSX      S4    *disabled
RP02      S4    *disabled  pci:0000:00:1c.1
PXSX      S4    *disabled  pci:0000:05:00.0
                *disabled  platform:rtsx_pci_sdmmc.0
                *disabled  platform:rtsx_pci_ms.0
RP03      S4    *disabled  pci:0000:00:1c.2
PXSX      S4    *disabled  pci:0000:06:00.0
RP04      S4    *disabled  pci:0000:00:1c.3
PXSX      S4    *disabled  pci:0000:07:00.0
RP05      S4    *disabled  pci:0000:00:1c.4
PEGP      S4    *disabled  pci:0000:08:00.0
PEGA      S4    *disabled
RP06      S4    *disabled
PXSX      S4    *disabled
RP07      S4    *disabled
PXSX      S4    *disabled
RP08      S4    *disabled
PXSX      S4    *disabled
EHC1      S0    *enabled   pci:0000:00:1d.0
XHC       S0    *enabled   pci:0000:00:14.0
TPD7      S0    *disabled
TPD8      S0    *disabled
HDEF      S4    *disabled  pci:0000:00:1b.0
LID0      S3    *enabled   platform:PNP0C0D:00

If I do this  "echo XHC > /proc/acpi/wakeup"
My sleep works correctly

I try to add this service to systemd:

[Unit]
Description=Disable USB wakeup triggers in /proc/acpi/wakeup

[Service]
Type=oneshot
ExecStart=/bin/sh -c "echo XHC > /proc/acpi/wakeup"
ExecStop=/bin/sh -c "echo XHC > /proc/acpi/wakeup"
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

When I reboot the system and check the wakeup stats, i see that XHC are disabled, but when I run a sleep comand, it does not work (instant wakeup)
My sleep only works when I manually change the XHC status to disabled.

Anyone can help me? Thanks to all.

Re: Disable USB 3.0 trigger wakeup after sleep

The thing is a toggle but your service toggles on start AND stop… so probably you're simply re-enabling it at some point (after looking at it)
Also this is likely triggered by just one naughty device. If you can isolate it, see https://wiki.archlinux.org/index.php/Ud … USB_device

In any case you should edit your post and stress that this is not about S3 wakeups, but a systemd service…
