Frank, take a look at comment #51 in
https://bugzilla.kernel.org/show_bug.cgi?id=43081
(near the end of the bug report). Does it do what you want?
Does anybody know if the +5VSB line is supposed to remain powered when
the computer is shut down (G2/S5 state)? Maybe that's the bug in
ASUS's ACPI implementation, and to work around it they avoid using
+5VSB for OHCI.
