Capture Device keeps shutting off

    Hello,


    I'm having issues where it looks like my capture device is shutting down. I have tried trouble shooting but I'm still having the issue. I have modified the config.txt for max_usb_current=1 but it appears that the device keeps shutting off. I can reboot the device and it will run for a few minutes and then shut off again. I am running on a Raspberry pi Zero. Any advice other than upgrading the Pi?

    This is the capture card I am using.

    Here is a link to the

    stick the capturing device into the USB2.0 slot and try again.
    if that's no sollution then update the firmware

    first.

    sudo apt-get update
    sudo apt-get upgrade

    these commands will push the new updates to your machine> when connected to internet ofcourse
    for the rest what to do, let me have a look

    try this

    apt-get install hdmi2usb-mode-switch

    if that doesn't work, SSH or terminal
    apt-cache search firmware

    find these 2
    1. hdmi2usb-fx2-firmware - FX2 firmware for hdmi2usb board development
    2. fxload - Firmware

    try the last post that I posted there.

    I'm still seeing the same error in the logs.


    The LED's run for about a minute and then everything on the display goes blank for a few seconds and then video comes back on but the LED's do not.


    If I toggle the GPIO status from off to on the LEDs come on for a few seconds and then the same problem happens. Screen goes black LEDs go off then after a few seconds the video comes back and the LEDs stay off.

    The issue has gotten worse. I'm wondering if it is a power issue. Now with the GPIO off it appears the capture card stops (loosing video) and then comes back a few seconds later. This happens every 30 seconds or so. I'm going to bypass the capture card until we can figure out what is causing the issue.


    Could it be power related? Is the Pi Zero able to power the capture card and the LEDs?

    I have the same problem :(
    After Minutes the Grabber seems to shut off. First I thought this is an hardware problem so I've bought another Grabber (WisFox).
    But the problem still stays on, till today.

    Everything works on an Pi Zero W.

    okay, i am running a Raspi 3b and Hyperbian version 2.013 and never had a problem.

    i use a external grabber 2.0 USB ( coffee black) on USB port 2.0



    i think your problems come from the fact that external grabber 3.0 doesn't run well on 2.0 USB port.



    see this article: https://s4scoding.com/what-usb…-are-on-the-raspberry-pi/

    means: its not receiving frames from the USBdevice, raspi is not recognizing the device.


    you can also determen that with this code:


    Code
    lsusb

    or


    Code
    dmesg

    no, execute them in the terminal or SSH with program Putty >> port 22


    if the device (vendor) is visble then you can see the device as MAC adres, first 6 digits is the vendor of the device. if not shown at all then the device is not recognized by the OS of the Raspi. This problem can be that Raspi is not powerfull enough in power/data to engage the Grabber because its 3.0 USB protocol and Raspi wants to run only 2.0 USB.



    OR/AND


    i would recommend writing a new image of Hyperbian version 2.013 >> do NOT format the SD card but write it on empty volume!



    goodluck.

    This is resolved. I determined that the issue was that they power source for the pi was not providing enough power. I was trying to run it off of the same power supply that was running the LEDs. I moved it to it own dedicated power supply which is running off of the USB port on the TV. Since doing that I have not had any problems.
