The attributes from the "msecli" tool show that this device uses NVMe 
instead of SATA internally. If none of '-d sntasmedia', '-d sntjmicron' 
or '-d sntrealtek' smartctl options work, this USB->NVMe bridge it is 
still unsupported. This cannot be fixed by drive database.

The latter is unrelated because very old and therefore likely an 
USB->SATA bridge, see https://www.smartmontools.org/ticket/133

This proves that there is some vendor specific NVMe pass-through 
functionality available. Cannot be implemented in smartmontools unless 
someone provides documentation or sample source code.
