Unfortunately i don`t know what caused the magic of self-repair of my device. So I can`t give you an advice what to do.

Werner and Igor, thank you for your answers! Some unknown magic happened during the last three days while the computer being switched off: All USB-devices are working fine now. Why it did not work last friday -- even after some reboots -- will always remain a mystery.

Hello, after upgrading the Odroid C2 to the current Version on 16.08.2024 the USB-devices do not work at all. According to the diagnosis information they are recognized during during bootup. But later they are disconnected for an unknown reason. https://paste.armbian.com/jucovipaxo lsusb only lists two devices: Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub The suggested hack "usbcore.autosuspend=-1" for USB-problems is already activated, but USB doesn't work anyway Maybe there is a solution for this strange behavior of my C2.
