That's interesting, it appears I may have been slightly mistaken. As per https://www.smartmontools.org/wiki/USB https://www.smartmontools.org/wiki/USB: > To access SMART functionality, smartmontools must be able to send native ATA or NVMe commands directly to the drive. For USB devices, at least the following conditions must be met: > The USB bridge provides an ATA or NVMe pass-through command. > This command is supported by smartmontools. > The operating system provides a SCSI pass-through I/O-control which works through its USB-layer. > SCSI support is implemented in the operating system interface of smartmontools. So in some cases, it may work depending on the USB chipset capabilities. I haven't gotten it to work on my old supermicro.. yet :) Cheers.
