MMM-PIR-Senor shut off usb port(s)
-
Hello,
I think it would be nice, if the usb port is shut down, when the monitor turns of. I have some speakers on my MM via usb and they make some noise. When it is still in the night you can hear it.
It it possible to cut of the energy supply to one or two usb ports?Sebastian

From the quick googling I’ve done, it may be possible to disable/enable raspberry pi usb power with commands:
Disable
echo 0x0 > /sys/devices/platform/bcm2708_usb/buspowerEnable
echo 0x1 > /sys/devices/platform/bcm2708_usb/buspowerHowever I haven’t tested. I’d recommend writing a new module that handles this and listens for the
USER_PRESENCEevent notification that the Pir module triggers.
