[mythtv-users] Suspend to ram with IONITX

OK, I got suspend to ram to work with my new diskless FE based on the
IONITX. I couldn't do this with my old frontend as it could shut down
(appletv) and this is my first foray into setting this up.
I hibernate to ram, works fine, but have to press the power button to turn
it back on.
System comes up and remote and audio work, which are 2 things I read people
have trouble with after resume.
I was looking up resume from USB/remote with the IONITX boards when I found
an "official" thread about the IONITX boards. From this thread I found out
that the original boards did not have the capability, crap. But, they
recently added Wake-on-USB on the V 01 boards. I checked, and I have it. It
is on by default, the JP3 jumper (only on the V 01) is set to 5V Dual by the
# cat /proc/acpi/wakeup
Device S-state Status Sysfs node
SMB0 S4 disabled pci:0000:00:03.2
USB0 S4 disabled pci:0000:00:04.0
USB2 S4 disabled pci:0000:00:04.1
US15 S4 disabled pci:0000:00:06.0
US12 S4 disabled pci:0000:00:06.1
NMAC S5 disabled pci:0000:00:0a.0
PBB0 S4 disabled pci:0000:00:09.0
HDAC S4 disabled pci:0000:00:08.0
XVR0 S4 disabled pci:0000:00:0c.0
XVR1 S4 disabled
P0P5 S4 disabled
P0P6 S4 disabled pci:0000:00:15.0
P0P7 S4 disabled pci:0000:00:16.0
P0P8 S4 disabled pci:0000:00:17.0
P0P9 S4 disabled pci:0000:00:18.0
PWRB S4 *enabled
So I do
# echo "USB0" > /proc/acpi/wakeup
# echo "USB2" > /proc/acpi/wakeup
# echo "US15" > /proc/acpi/wakeup
# echo "US12" > /proc/acpi/wakeup
And now I have
USB0 S4 enabled pci:0000:00:04.0
USB2 S4 enabled pci:0000:00:04.1
US15 S4 enabled pci:0000:00:06.0
US12 S4 enabled pci:0000:00:06.1
I then hibertate to ram, and watch as the system suspends and then resumes
itself without prompting from me.
Process of elimination identified the issue as US12 being enabled for
resume. Incidentally this is the one that the Streamzap is plugged into. So
I switch it, it is now in USB2, and the same issue again. This time tracked
back to the USB2 being enabled???
Does the Streamzap not support suspend?
If so, which remote do people recommend for resume?
