Orange Pi AI Stick 2801 - can not open file:/dev/sg2

I purchased both
'Orange Pi AI Stick 2801 Neural Network Computing Stick Artificial Intelligence' and
'Orange Pi AI Stick 2801 with PLAI Model Transformation Tools Neural Network Computing Stick Artificial Intelligence'.

'OrangePi AI Stick_X86 Demo executed according to User Manul (For Ubuntu 16.04)' but core dump.

# l /dev/sg*

There is no '/dev/sg1' and '/dev/sg2'.

Where is ’PLAI Model Transformation Tools’ ?
Do I need to install a driver etc. before the procedure of 'User Manul' ?

I changed to /dev/sg0 and it worked.

During execution, the following log appears in Journal, is it such a thing?

I thought that ’PLAI Model Transformation Tools’ was inside the Ai Stick. However, software had to be downloaded separately. About 11GB.

I will create a dedicated driver. Or Journal error will not disappear until 'Ai Stick' function driver corresponds to generic SCSI command...
I wish I could return the dummy MBR...

I tried it with 'Orange Pi 3 Memory 2 GB'.
In x86_64 and aarch64 version, it seems that the way of demonstration software display is slightly different ...

For your reference...
Gnet1:  FrameRate 10, CNN 27, FC 65
Gnet18: FrameRate 37, CNN 24, FC 1.4

Thank you.

Adding udev's rule makes me happy a bit.
