Can't disable USB wakeup

[duron600]

Trying to hibernate Tumbleweed seems to work (black screen), but then the "screen before the login screen" pops back up - so hibernate fails.

It seems like it is being woken up right after hibernate. Same two times.

Swap partition is 8.3G, 8G memory.
Before hibernating, changed bootloader to

resume=/dev/mapper/cr_sdb6 splash=silent quiet showopts

as that is the swap partition name.

cat /proc/acpi/wakeup
EHC1 S4 *enabled pci:0000:00:1d.0
EHC2 S4 *enabled pci:0000:00:1a.0
XHC S4 *enabled pci:0000:00:14.0

(rest disabled).

Trying to disable fails on permission denied:

sudo echo EHC1 > /proc/acpi/wakeup
bash: /proc/acpi/wakeup: Permission denied
echo EHC1 > /proc/acpi/wakeup
bash: /proc/acpi/wakeup: Permission denied

What can I do to enable hibernation?

Is there a good plan B alternative to hibernation?

Thanks.

If you're using sudo, try it like this

sudo sh -c 'echo EHC1 > /proc/acpi/wakeup'

Note: This won't persist through a reboot, so if you need help with making it permanent let us know.

Thanks.

I tried just waiting longer and then it seemed to work and has since.

Yep, but you can't use sudo in the way that you were trying to do. It won't persist through a reboot either. It needs to be added via an init script eg boot.local.
