Wake on USB no Thinkpad W541

Question

Eu estou tentando configurar o wake-on-usb no meu Thinkpad W541 com Fedora 26 no kernel 4.14.18-200.fc26.x86_64. Depois de googling ao redor eu fiz

echo enabled > /sys/bus/usb/devices/**/power/wakeup
echo on > /sys/bus/usb/devices/**/power/control

para todos os dispositivos em usb3 e confirmou que informa enabled / on . Este é o meu lsusb -t quando sentado na estação de encaixe:

/:  Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M

Eu estava experimentando com diferentes configurações hw, tentando o mouse com fio conectado a portas de laptop, o acima está na estação de encaixe em uma porta sempre ativa (amarelo). Nada funcionou até agora. cat /proc/acpi/wakeup me dá

Device  S-state   Status   Sysfs node
LID       S4    *enabled   platform:PNP0C0D:00
SLPB      S3    *enabled   platform:PNP0C0E:00
IGBE      S4    *disabled  pci:0000:00:19.0

EHC2      S3    *enabled   pci:0000:00:1a.0

e enquanto isso não mencionar USBx , o XHCI parece ser o correto, já que

lrwxrwxrwx. 1 root root 0 Jul  9 23:08 /sys/bus/usb/devices/3-9 -> ../../../devices/pci0000:00/0000:00:14.0/usb3/3-9

Quando faço systemctl suspend , a roda de rolagem do mouse é desativada, mas quando eu clico nela ela pisca novamente, então há alguma energia. Depois de começar a usar o botão liga / desliga, posso ver em dmesg :

Verifiquei se pm_qos_remote_wakeup e pm_qos_no_power_off estão definidos como 1 em todas as portas da estação de encaixe.

Eu passei pela BIOS, mas não vi nada que deveria estar relacionado ao wake on usb, apenas na lan (e essa configuração está ativada). Eu aprecio mais dicas.
