OP here. FWIW, this is what I get when running that command on the SCSI
generic device that corresponds to the USB-3 (non-UAS) disk[1] that had the
issue:

----
$  sudo sg_vpd -p bl /dev/sg4
Block limits VPD page (SBC):
  Write same no zero (WSNZ): 0
  Maximum compare and write length: 0 blocks
  Optimal transfer length granularity: 1 blocks
  Maximum transfer length: 8191 blocks
  Optimal transfer length: 8191 blocks
  Maximum prefetch length: 8191 blocks
  Maximum unmap LBA count: 0
  Maximum unmap block descriptor count: 0
  Optimal unmap granularity: 0
  Unmap granularity alignment valid: 0
  Unmap granularity alignment: 0
  Maximum write same length: 0x0 blocks
$

If more info is needed, just let me know.

[1] - SCSI generic devices follow "/proc/scsi/scsi" order, right?
