Video capture card don't show in pi zero w hyperion

  • If the grabber is not available for selection in Hyperion, it will not be available in your system.

    usb-devices |grep uvcvideo lists what is available.

    Use a different cable, USB port or grabber.

    Test the grabber on the PC/laptop to see if it works.

  • it's working very fine in PC but in hyperion not detected.

  • that's your USB Host controller from Linux itself.

    So it sees the controller but not the device connected to this controller.

    Try to update the firmware of the pi, look in my older comments to do that or

    open a new terminal window and entering the command sudo rpi-eeprom-update . If it flags that updatw is available, one option is to run sudo apt update followed by sudo apt full-upgrade to fully update your Pi's software, firmware included


  • I updated it by apt update & apt full-upgrade but it made no difference


  • try then to increase the USB port power.

    In config.txt add a line

    max_usb_current = 1

    and reboot with

    sudo reboot

    Try also to increase PI power onto 5.3 volts, if PI runs to low on voltage then USB port power is even lower then 600ma, so maybe only 4.8 volts and 400ma max

    Measure the power to the PI WITH load

    increase Raspberry Pi USB current limit - KaliTut
    how to increase Raspberry Pi USB current limit USB devices are powered almost without exception via the USB to whose host they are connected.

  • I use max_usb_current=1 and also use a powered usb hub but the problem still exist.

    also i think other than the capture card, other devices such as flash memory and wireless mouse adapter will not work.

    Does it need to activate anything?

  • Have you checked the voltage to the Pi as Lightning-guy77 suggested?

  • you can update the firmware of the HDMI and USB capture device port. Sometimes that will help to get it back on track again.

    Your capture device is recognised by Windows 🪟 so it shouldn't be a malfunction in the capture device I think.

  • stick the capturing device into the USB2.0 slot and try again.

    if that's no sollution then update the firmware


    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 download to EZ-USB devices

    and execute them

    code to install if found

    apt-get install hdmi2usb-fx2-firmware

    apt-get install fxload
