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
