I like to add my EnOcean devices to home assistant. For this I bought an USB 300 (see USB 300 - EnOcean) and added the EnOcean integration.
No devices appear even after switching the EnOcean devices on and off and on again.
Instead I see the follwing debug messages:
2024-01-21 10:29:00.344 WARNING (MainThread) [homeassistant.helpers.entity] Entity None (<class 'custom_components.hacs.update.HacsRepositoryUpdateEntity'>) is using deprecated supported features values which will be removed in HA Core 2025.1.

I can’t see if you are running HAOS on bare metal or a hypervisor.
If you are running on a hypervisor, then make sure that the USB device has been passed through to the VM.
Check the Settings → System → Hardware → All hardware to see if it is listed there.
