This is a follow-up to an issue I had a while ago but never had the time to debug it: [0] Short summary: - on Meson8b USB devices are only detected if they are plugged in before booting Linux - if they are plugged in after booting Linux they are not detected (except when running "lsusb -v" as a workaround) Christian Hewitt made me aware of a similar issue that was fixed for Rockchip devices. This single patch applies the same fix to the Amlogic devices as well.
