OK, I had to track down which package contains sg_readcap.
The adapter that fails gives this output:
# sg_readcap --16 /dev/sdb
bad field in READ CAPACITY (16) cdb including unsupported service action
The adapter that succeeds gives this output:
# sg_readcap --16 /dev/sdc
Read Capacity results:
Protection: prot_en=0, p_type=0, p_i_exponent=0
Logical block provisioning: lbpme=0, lbprz=0
Last logical block address=5860533167 (0x15d50a3af), Number of logical
blocks=5860533168
Logical block length=512 bytes
Logical blocks per physical block exponent=0
Lowest aligned logical block address=0
Hence:
Device size: 3000592982016 bytes, 2861588.5 MiB, 3000.59 GB
