Yes. This ID is already in drivedb.h because it reportedly works with -d 
sat option:

Possibly. Could you test the drive on a different machine?

This means that smartctl did not detect this device as USB.

Smartctl uses the following heuristics:
Follow the symlink "/sys/block/sdn" which is expected to point to some
"/sys/devices/pci*/*/usb*/*/*/host*/target*/*/block/sdn" directory.
Then check its parent directories for first idVendor and idProduct files.
These should contain the USB ID of the drive.

Please try:
ls -l /sys/block/sdn
find /sys/devices -name idProduct

Thanks,
Christian
