I can not check that now, the SSD that misbehaved if not connected via a 
powered USB Type C hub is not available to me now. I don't even know if 
I  would still have that particular problem now after having updated the 
firmware in the rtl9210 controller today.
It is very likely that the powered hub masked the real problem of an 
early and buggy firmware.

I propose that those who have a uas problem add a local quirk in their 
system.
If you google 0bda:9210 then you will find lot of people who have 
disconnect or no connect problem with their enclosure but you will also 
find lot of people who say that their enclosure works without any 
problems. They, and I, don't want your quirk in our systems..

Another option for you is to ask your mfgr for a firmware upgrade or
to search for and find one on the net (as I did).
The release notes especially mention fixes compatibility problems withr 
Samsung 980 pro and WD Black.
