In the code comments above the WARN, this condition indicates "the
discard granularity isn't set by buggy device driver". The block layer
needs this set if your driver also sets the max_discard_sectors limit.
Please provide the output of:
# sg_readcap -l /dev/sdN
# sg_vpd -l /dev/sdN
# sg_vpd -p 0xb0 /dev/sdN
# sg_vpd -p 0xb1 /dev/sdN

Thanks!
I am not in the office anymore, so I cannot plugin the USB device to run
the commands you requested. First thing tomorrow in the morning, promised.
