[x86-64] Setup for XHCI Suspend/Wakeup

LE_User_2025 · April 15, 2025 at 7:40 PM

Hello. Through some troubleshooting I found that disabling the XHCI wakeup allows my laptop to suspend and resume properly.

The issue is that I cannot figure out how to make this change permanent. I found some suggestions online but they don't seem to apply or correlate with how LE works.

Any suggestions or links are appreciated.

Guessing at the solution wastes time and sucks, so it would help if you posted info on the commands that work to disable it, and other links that helped you arrive at that solution.

LE_User_2025 · April 16, 2025 at 10:04 AM

Thanks for the reply.

These are the commands I used:

cat /proc/acpi/wakeup Shows the devices enabled/disabled states

/bin/sh -c '/bin/echo XHCI > /proc/acpi/wakeup' Toggles XHCI wakeup

Once it is set to disabled my computer will suspend and resume using a remote (which was my goal)

This post describes setting up the command as a service to load on boot:

[SOLVED] Suspend_Wakeup /proc/acpi/wakeup file / Kernel & Hardware / Arch Linux Forums

Here is another that suggests a different method:

I just do not know how to do these on LibreElec

Thanks again.

Create the custom systemd service as /storage/.config/system.d/xhci.service

Enable with systemctl enable /storage/.config/system.d/xhci.service

Start with systemctl start /storage/.config/system.d/xhci.service

Then check for errors. If you need to make changes and edit the file, run systemctl daemon-reload after the changes.

Aside from the odd /storage location, systemd things work the same as most other distros.

Thank you.

The first command to enable the service was successful.

Attempting to start it resulted in this error:

Failed to start storage-.config-system.d-xhcidisable.service.mount: Unit storage-.config-system.d-xhcidisable.service.mount not found.

I also tried systemctl enable xhcidisable.service and then systemctl daemon-reload which did not give any errors.

But after restarting the computer and using cat /proc/acpi/wakeup I can see that XHCI is not disabled.

XHCI S3 *enabled pci:0000:00:14.0

I used systemctl status xhcidisable.service

and got:

○ xhcidisable.service - no_usb_wakeup

Apr 16 08:45:09 LivingRoomKodi systemd[1]: xhcidisable.service: Deactivated successfully.

I tried the command /bin/bash -c "echo XHCI >> /proc/acpi/wakeup" on it's own which does work.

Could the service be executing in the wrong order with something else?

I apologize for my ignorance of Linux. I know some things about it but I mostly work with Windows.

Share the contents of the /storage/.config/system.d/xhci.service file you created.

LE_User_2025 · April 16, 2025 at 6:39 PM

Sure here you go:

[Unit]
Description=no_usb_wakeup

[Service]
ExecStart=/bin/bash -c "echo XHCI >> /proc/acpi/wakeup"

[Install]
WantedBy=multi-user.target

Oh and I should mention that I created the file using the SMB share under \\share\Configfiles\system.d\ from my Windows PC.

Also, the file I created is called xhcidisable.service

Create that ^ as /storage/.config/udev.rules.d/30-disable-wakeup.rules but ensure you do this via SSH/nano to ensure unix line endings are used (as Windows endings will not work). You can stop/disable and then delete the systemd service file.

Working?

LE_User_2025 · April 17, 2025 at 1:32 PM

Okay I've created the file and then restarted but XHCI was not disabled.

Is there anything else I needed to do to enable the new script?

Code

Change 'echo disabled > /sys$devpath/power/wakeup' to 'echo XHCI >> /proc/acpi/wakeup' and try again.

LE_User_2025 · April 18, 2025 at 12:04 PM

Thank you. Unfortunately that didn't seem to work either. And I'm not sure if this is related or matters but now EHC1 is enabled. As far as I can remember it has been disabled every time I've looked at them. I rebooted a couple of times just to make sure.

Code

LivingRoomKodi:~ # cat /proc/acpi/wakeup
Device  S-state   Status   Sysfs node

In this post the user recommended putting a script in /usr/lib/systemd/system-sleep/ which would check if it's enabled and if so would disable it before suspending.

However, I was not able to add a file to this directory. Is there another location for this or is it not possible on LE?

Use /storage/.config/system.d/

LE_User_2025 · May 19, 2025 at 9:13 PM Best Answer

Okay I finally had some time to try solving this issue again. Here is what ended up working:

Created the file (using nano):
/storage/.config/system.d/xhci_disable.service

Pasted this content:

Code

[Unit]
Description=Disable XHCI Wakeup
[Service]
ExecStartPre=/bin/sleep 15
ExecStart=/bin/bash -c "echo XHCI >> /proc/acpi/wakeup"
[Install]
WantedBy=multi-user.target

Enabled the service with:
systemctl enable /storage/.config/system.d/xhci_disable.service

Rebooted and checked status with:
cat /proc/acpi/wakeup

Seems to be working correctly now after testing multiple reboots and suspending/waking.

Anyway hopefully this is helpful to someone in the future and thanks for taking the time to reply and make suggestions.
