Am un Dell 9020m cu 6 porturi USB (4 in spate, doua in fata). Sistemul de operare este Debian 11 stable cu update-urile la zi.
Problema e ca atunci cind pun sistemul in suspend, porturile USB sint inca alimentate. Ciudat, dar nu am gasit in BIOS vreo optiune care sa controleze asta (de regula poti lasa un singur port alimentat permanent, daca vrei asta).

Configuratia hardware este:

# lsusb | sort

In mod normal am un soarece si o tastatura conectate printr-un hub USB pasiv - Terminus Technology Inc. Hub.
Configuratia raportata de uhubctl este diferita:

In teorie, tot ce am de facut ar fi sa opresc alimentarea pentru usb2 device 8 (terminus), dar obtin doar asta:

Quote

# echo suspend > /sys/devices/pci0000:00/0000:00:14.0/usb2/2-8/power/level
bash: echo: write error: Invalid argument
Din ce am cautat pe Google, aparent asta ar fi un read-only filesystem si nu prea pot schimba asta.

Aceeasi eroare o obtin si daca incerc:

Quote

# echo 0 > /sys/devices/pci0000:00/0000:00:14.0/usb2/2-8/authorized
# echo suspend > /sys/devices/pci0000:00/0000:00:14.0/usb2/2-8/power/level
bash: echo: write error: Invalid argument
Detalii aici: https://github.com/mvp/uhubctl

Am incercat sa opresc si toate (da, toate) porturile USB:

Quote

uhubctl -a on -p 8 -l 3-1
Intr-adevar, porturile sint afisate ca oprite, dar tot nu am reusit sa imi tai craca, adica sa opresc mouse-ul si/sau tastatura.

Am incercat si cu powertop, am pus toate porturile pe autosuspend, dar tot degeaba.

As aprecia orice sugestii si hint-uri.

In bios nu ai optiunea Eup? Eu de acolo le am dezactivat.

În BIOS - Power Management, pune Disable pe USB Wake Support from Standby (S3), respectiv Hibernation (S4)

Daca EuP inseamna Energy-using Products, nu am gasit optiunea asta.

@m-amintors & mhanor setarile de power management sint astea:
- Deep sleep control -> Enabled in S4 and S5
- Block sleep -> Disabled (pot sa-l pun si pe enable, nu schimba nimic)
- USB wakeup -> Disabled
