No, it won't do any of that unless CONFIG_USB_SUSPEND
is enabled.  I've certainly observed the PME# bit be set
in the PCI config space after forcing the HCD to put such
controllers into D3hot through sysfs.

But note that the whole USB wakeup mechanism happens to
be marked EXPERIMENTAL.   It's been tested in isolation,
but not integrated with things like S1 or S3 sleep ...
and the last time I tried to enable ACPI wakeup (with
the /proc/acpi/wakeup file), it didn't work at all.

... etc.  FYI it's much easier to understand "lspci -vv"
than the hex dump; pass "-xxx" if you like too of course.
