USB device yoctopuce

  • I am trying to use a yoctopuce board (altitude to start with) on the USB A port of the dock board with an Omega2+.
    And using python. It complains that libusb-1.0.so.0 is absent. At this point I have resorted to using a pi instead.
    Is Omega supposed to be able to work the yoctopuce devices?

    Does the file /root/cdll/libyapi-mipsel.so actually exists? If it does exist check your symlinks, libusb-1.0.so.0 may not exist.

    You can troubleshoot loading the so by using insmod to report any missing dependencies.

    /root/cdll/libyapi-mipsel.so is present.
    libusb-1.0.so.0 does not exist.
    I don't know how to obtain a libusb-1.0.so.0 for omega+.
    I have still given up trying to fix this.
    Somebody else, though, might want to use yoctopuce with onion.

  • @Michael-Mayo

    libusb-1.0.so.0 is a symlink to the so, you can just create it :

    cd /lib
    ln -s libusb-1.0.so libusb-1.0.so.0
