Please provide the USB ID of this device. Smartctl should print it if no 
-d option is specified.

The 'auto' flag for '-d sat' would only work if vendor name "ATA " is 
returned via SCSI INQUIRY. This is the case for SATA drives behind SAS 
controllers. USB bridges usually return some real vendor name and 
smartctl selects -d scsi.

This error message suggests that this USB bridge does not support the 
SAT ATA PASS-THROUGH(12) command.

Due to '-T verypermissive' option, smartctl ignores the error and prints 
useless info from a zero filled IDENTIFY data block.

Same problem with SAT ATA PASS-THROUGH(16) command.

Many Seagate USB drives support SAT, this one apparently doesn't.
