usbAutorun script is part of the package omega2-usb-autorun.

By default omega2-usb-autorun is not part of the firmware.

Can you try the following steps?

1. Unplug USB
2. Install omega2-usb-autorun

opkg update
opkg install omega2-usb-autorun

3. Plug USB

@jempatel i believe this is referring to automatic mounting of usb volumes.
Not our custom autorun of scripts on usb storage

@jempatel I am aware you were away for a while, so please provide a status update on this ticket.

@mh1412, there may be an issue with your USB device file system. I formatted my usb (for the test) to use ntfs, ext4, fat32, exfat filesystem types. Automount worked perfectly for ext4 and fat32 but failed for ntfs and exfat. And this is because there was no such kernel module installed for NTFS and exFAT. When I loaded them - I got success. I used onion_omega2p-22.03.3-20230526.bin firmware

@amsiotdeveloper can you please make a new documentation task to add the solution to this mounting problem to the documentation
