Silicon Dust HDFX-2US avahi

OpenWrt 23.05.0 r23497-6637af95aa
vlans 1 and 3

I installed/configured avahi and umdns
If I run "ubus call umdns update" and then
"ubus call umdns update"
I see lots of devices on both vlans and both ip4 and ip6
But my Silicon Dust HDFX-2US is not listed
Does anyone else have 1 of these devices ?
