i got some error on this line when loading the USD. It appears that it cannot find the stage layer from the loaded usd(which is weird as it should be using the staging layer which is newly created)
During load error happened on Product: "usdAsset" Representation: "usd" Version: 7

Does it mean it is only allowed one geometry in the loaded asset(or can we load with multiple assets)? Maybe we can exclude some families to load this as we can load stuff via this loader if it is also layout product(which is mostly with multiple assets).

The error means that you need to SELECT a PRIM inside the Maya USD Proxy to 'reference into'. Unfortunately since it 'references into a prim' there isn't really something more intuitive I could think of whilst still allowing to load anywhere inside the USD hierarchy.
