This would be a question for the Synology community, however they mainly use USB hubs for hard drives.
I just wanted to know if it’s worth trying to get it to work.
So does anyone have 2 optical reading heads running at a USB hub on a Synology NAS? Directly on the USB port only one is working. Both on the hub are recognized but no data is received at ttyUSB0 or 1, permissions are set:
chown -R openhab.uucp /var/lock
chmod -R guo+w /var/lock/
chmod 0777 /dev/ttyUSB*
chown openhab:users /dev/ttyUSB*```
