I do no really understand your question. It might be my english.
Every of tested USB (2 of 5) ports is working for wake-on-usb. It
works for suspend-to-ram (S3), suspend-to-disk (S4) or shutdown (S5).
I just turn it on for every USB port in /proc/acpi/wakeup.
root at mythbox:~# cat /proc/acpi/wakeup
Device S-state Status Sysfs node
HUB0 S5 disabled pci:0000:00:10.0
XVRA S5 disabled
XVRB S5 disabled
XVRC S5 disabled
UAR1 S5 disabled pnp:00:09
UAR2 S5 disabled pnp:00:0a
PS2K S4 enabled pnp:00:0c
USB0 S4 enabled pci:0000:00:0b.0
USB2 S4 enabled pci:0000:00:0b.1
AZAD S5 disabled pci:0000:00:10.1
MMAC S5 disabled pci:0000:00:14.0
MMCI S5 disabled
as you can see PS2K, USB0 and USB2 are enabled. is says S4 for State,
but it is working for S3 and S5 also. you can enable your usb ports
with these commands. put them in rc.local, because these settings are
getting reseted after every reboot.
## wakeup commands
echo PS2K >/proc/acpi/wakeup ## PS2 keyboard (Ctrl+Esc for wake-up)
echo USB0 >/proc/acpi/wakeup ## USB
echo USB2 >/proc/acpi/wakeup ## USB
## wake-on-lan activation
/usr/sbin/ethtool -s eth0 wol g
