  • Power off USB ports during standby

    Well,

    I never had issues with the temperature of the STB itself. More with the temp of the CAM burning my smartcard (see attachment) or getting unresponsive. I thought that putting a fan could relieve a bit the situation.


    I've tried to install manually that plugin but I get an error.

    So I did

    Code
    opkg install hddtemp


    but it didn't help. From telnet, hddtemp /dev/sda1 reports the temperature correctly.

    Any advice?

    In any case, this plugin doesn't seem to handle USB external fan, but rather internal fans (or at least plugged directly on the motherboard)

  • Power off USB ports during standby

    It sounds to me strange that power management is not within the options available, not even from command line.

    At the end of the day, there is also an EU norm about max standby power allowed, isn't it? Like any modern computer, there are options to turn off USB power during standby.


    Use case: I have problems with high temperature (mostly the CAM get stuck and smartcard has signs of browning :( ) and I placed a USB-powered fan to cool down everything. Of course, during standby, I have no reason let the fan on without counting the noise made. During watching TV noise isn't an issue but when the TV is off, noise id perceivable.

    Thank you. I appreciate!
    However it doesn't work :(

    On the one hand:


    Code
    echo -n "usbX" | tee /sys/bus/usb/drivers/usb/unbind
tee: /sys/bus/usb/drivers/usb/unbind: I/O error


    However,

    Code
    echo -n "usbx" > /sys/bus/usb/drivers/usb/unbind

    was successfull.


    On the other hand

    Code
    root@vuuno4kse:~# ls /sys/bus/usb/drivers/usb
5-1     bind    uevent  unbind  usb3    usb4    usb5    usb6


    So I have tried to unbind everything:

    Code
    root@vuuno4kse:~# echo -n '5-1' > /sys/bus/usb/drivers/usb/unbind 
root@vuuno4kse:~# echo -n 'usb3' > /sys/bus/usb/drivers/usb/unbind 
root@vuuno4kse:~# echo -n 'usb4' > /sys/bus/usb/drivers/usb/unbind 
root@vuuno4kse:~# echo -n 'usb5' > /sys/bus/usb/drivers/usb/unbind 
root@vuuno4kse:~# echo -n 'usb6' > /sys/bus/usb/drivers/usb/unbind

    however, power it's still delivered to USB ports.

    I'm keen to thinks than unbind is like "Eject" in windows/mac which doesn't remove power from USB.

    Any other ideas?

  • Power off USB ports during standby

    Hi there,


    I'm looking for an option to power off USB ports during standby. I'm not talking about "deep standby" because I want the timers still processed during "off" period.

    I'm on openATV 7.4.20240807 and Vu+ Uno4K SE.

    Any idea on how to get it done? I'm not afraid to use terminal commands, if needed.


    Thanks in advance
