On the Orico M.2 NVME SSD enclosure which claims to support UASP, trim
did not work on a fresh Ubuntu 24.04 install until a rule was added to
/etc/udev/rules.d. The lsblk --discard sda output also listed a DISK-MAX
of 0 for all partitions. After the rule (below) added (with proper
vendor and product ids from lsusb), the DISK-MAX was 4G and fstrim
succeeded. See Allen's 2020 answer on

usb-3-0-enclosure-does-not-work-uasp-not-supported
