 The ACU sends a couple of `IOCTL_SCSI_MINIPORT` IOCTLs with custom payloads on controller selection; this is received and handled by the `HpSAMD.sys` driver. So far cross-checking the payload format with the well-known Linux sources hasn't yielded any success; I assume when `IOCTL_SCSI_MINIPORT` is used, the payload isn't what 1:1 gets sent to the controller, unlike `IOCTL_SCSI_PASS_THROUGH` which isn't what the ACU uses. Next step might be trying to port over the Linux CCISS example requests to the Windows SCSI API by using `IOCTL_SCSI_PASS_THROUGH` to try if the controller then responds with the same packet structure as it would under Linux.
 
+So far trying to get a `IOCTL_SCSI_PASS_THROUGH` for controller identification to work results in a `ERROR_IO_DEVICE` 1117 (0x45D).
