Thanks,
I would have tried, but don't have my libreELEC up and running yet.
Is LibreELEC also Debian based? Or even Raspbian based?
Anyway, I think this is useful info in general, as with the proliferation of Model 3 more and more setups might not need these interfaces either, and 200 mA is not peanuts!
I know # is a comment, I put it in there myself, wasn't in my source I'd figure why not put workable code (resp. usual convention wrt. $-prompt) if using the [[Code]] tag.
Maybe if you described how it's done in Raspbian.
So, this is how you do it on Rasbian. What do you do for LibreELEC?
As root:
#!/bin/bash
# disable
echo 0 > /sys/devices/platform/bcm2708_usb/buspower
# enable
echo 1 > /sys/devices/platform/bcm2708_usb/buspoweraccordingly, from a normal ssh, at the prompt session that would be:
$ # disable
$ sudo sh -c 'echo 0x0 > /sys/devices/platform/bcm2708_usb/buspower'
$ # enable
$ sudo sh -c 'echo 0x1 > /sys/devices/platform/bcm2708usb/buspower'Alternatively instead of buspower there is also bussuspend, but that one cannot be reactivated, only by a reboot.
See also here (Stackexchange) -- the chip alone draws 200 mA!
The combined USB/Ethernet chip (LAN9514) is a known power leech on the RasPi_s, and power consumption is a concern in my setup.
In my setup, now having Raspi 3 I do not need either the Ethernet port, nor the USBs (networking over WiFi, which is onboard now (on a separate chip), so no need for a USB dongle).
I know how to power down the LAN9514 in a Raspbian distribution, however I have no idea how to achieve this in LibreELEC.
Does anyone know?
