I have made by my self this cooling system its very simple but that what I need its if exist any mode to stop this fans when my DM800 HD goes in standby mode or shut down. Any detailed technical suggestions are welcome. Thanks

On usb i don't think so !
there is a modification using the power from scart socket, but much complicated.
Otherwise, simple disconnect the usb when you put in standy.

yeah I know but I am searching for an automatic system it will be more interesting.

Pull the power (+) off pin 8 of the scart.

Yes @cokesux..... pin 8 and ground (pin 9 or 13 or 4), thats all.

Nah I need it without modify anything inside of my box. But anyway thanks.

or use a power adapter, example 9 volt

The easiest way is to fix a mini switch on the cable providing power ans simply switching it off.

I do not know if a script is available to power off the unit.

this is a very good idea, if you are lazy and dont want to move to turn off the switch, buy a switch with a remote control to power it off while you are relaxing on your soufa !!!

But if I develop a linux script that power off the usb ports can any one here convert it in enigma2 plugin ?

 

[Hell-o]

this is one example: lsusb -v | less

You should be able to power it off with:

echo "0" > /sys/bus/usb/devices/device/power/state

For example:

echo "0" > /sys/bus/usb/devices/6-0:1.0/power/state

I think it will be utile to have a plugin that control usb power to switch it on and off.

On my DM800, I have this configuration connected to an internal fan.
It is working all the time, but it is quite and is keeping the box cool.
So no complain.​

Yes BM300 I know this modification but I use the scart to connect my headset throw a RCA modification so I cant connect fans there.

But you can my friend.
Connect the wires from inside the receiver.
You can still use the scart connecter in the normal way.​

 

[passete]

yes, but you get noise (electronic noise) from the fan !
And if you use headset, the noise is unbearable.

Good point.​

let the 12v scart control a relay who switch the power from usb on of

You can try to use the internal usb port connector.
