libreelec 11 with AX88179 based USB to Ethernet Adapter unstable

    The ethernet adapter ( https://www.amazon.com/UGREEN-Network…uage=en_US&th=1 ) used to work fine on my libreelec 10 installed on an Dell Inspiron 11 3168 . I freshly installed libreeelec 11 release on the laptop and it stopped working. "Wired Networks" option won't appear in network settings anymore.

    I found a workaround though:

    1. boot libreelec 10 in live mode on usb stick

    2. once in kodi reboot your machine using kodi ( dont use "Power off system" !! ) , remove your libreelec 10 live usb stick and boot your hard disk installed version of libreelec 11 in UEFI mode

    3. for some reason the ethernet adapter will blink again and "Wired Networks" will appear in settings

    My knowledge is limited on how linux detects devices and loads corresponding modules/drivers but here are some additional infos that might give some insight.

    With an non working adapter on libreelec 11:

    lsusb detects the device.

    dmesg | paste :

    plugging unplugging the adapater triggers:

    [ 245.105441] usb 1-2.2: USB disconnect, device number 5

    [ 247.376395] usb 1-2.2: new high-speed USB device number 10 using xhci_hcd


    When the ethernet adapter is working after rebooting from libreelec 10 dmesg adds the following traces on libreelec 11 ( dmesg | grep ax88) :

    Any ideas on how this could be fixed?
