At first glance, it works well.
Did the driver load itself at boot, or did you start it manually with modprobe?
In the meantime, I backported the persistent journal option to 9.2.8.10, so you can now send me a full system log.
You can turn this on under Settings -> LibreELEC Settings -> System -> Logging.
This setting requires a reboot, after that please send a link generated by journalctl | paste. Thanks.
