Hi,

Currently i'm working on sending query request upiu to ufs device by using DeviceIOControl(IOCTL_STORAGE_PROTOCOL_COMMAND) but i'm getting ERROR_INVALID_FUNCTION on getLastError(). Can you please provide sample code or documentation on DeviceIOControl integrate with UFS Device.

Thanks for support.

IOCTL_STORAGE_PROTOCOL_COMMAND should only be used for vendor-specific commands. I suggest you could refer to the Doc:Using IOCTL_STORAGE_PROTOCOL_COMMAND to send commands
