I am trying to implement the Sanitize and Firmware Upgrade commands for an external card connected via the Thunderbolt Interface (4.0) Should we consider writing a Kext based off IOBlockStorageDriver or IOPCI interface. NVMController does not expose anything more than the 3 API.. SmartReadData, getLogData and getIdentifyData. The device is connected only on MacOS.(mini and macbooks)
My ioregistry look like :
