I'm currently trying to configure the Zephyr HCI USB sample to allow using legacy and extended advertising. Currently when I build the sample with extended advertising enabled and I issue a legacy advertising HCI command I always get a response of COMMAND_DISALLOWED. When I change the config to not build with extended advertising the HCI command works and I can see the advertisements. Is my configuration wrong, or is this not possible.
I'm using NCS v2.8.0 with the following prj.conf for the HCI USB sample:

Below see the output of btmon on the host that is issuing the HCI commands.
