  • Unable to connect to host.

    I might have solved the issue... after increasing the usb power output by adding the line "max_usb_current=1" as well as "hdmi_force_hotplug=1" in the config.txt the grabber could pull an image again and the ambiligt works again.


    Still strange that it used to work wihtout this but at least it is functioning again.
    Hope this does the trick for you aswell!

  • Unable to connect to host.

    Heyhey,


    I just signed up here because I started having a similar problem a couple of days ago.
    I built the Ambilight using a raspberry Pi 3 B+ with APA102 LEDs and it worked like a charm the first time right away.


    Since yesterday i now have the problem that after the start-animation (Rainbow) the LEDs turn off even with an active HDMI input source.
    I also had the issue that I got the "unable to connect to host" message whenever iI tried sending a color from either Hyperion on my laptop or the App.


    After disabling the grabber and transferring the new config-file, sending colors worked again.
    Now I can also enable the grabber in the settings again, send this config-file and sending a color still works.
    Nontheless the Ambilight does not react to any image from the HDMI input.


    Additionally i noticed that when I try to "get image from grabber" in Hyperion the program seems to freeze and I have to force close it.
    Occasionally i get an image from the grabber which then is full of artifacts (stripes, wrong colours, image consists of several incorrectly combined pieces etc.).
    The Pi seems to be working nominally, though.


    Now my first thought after the Pi with the grabber dropping once from the back of my TV (Velcro Tape not strong enough) being the only "change" that happened, that one of these devices stopped working properly.


    Therefore I tried:
    - rewriting the raspbian image and reinstalling Hyperion
    - replacing the grabber
    - replacing the Pi


    Result: Nothing but still having the same issue.


    Now the only other components that could in my opinion be a cause for this (IMO) that I haven´t switched out, yet are the HDMI2AV converter and the Chinch-adapter or it has to be a software issue.


    Have you or anybody else here gotten any further or an idea what could cause this?
    It was really a fun project to build and I´d really love getting it to work again.


    I have added a log and my config below.


    Thank you all in advance and have a nice weekend.
