DJM-A9 USB connection with a computer

When connecting the DJM-A9 with a computer the USB LED is binking blue when a connection is established. This is different from the behaviour of the DJM-900nxs2 where the LED lights up solid when connected to a computer.
Honestly the blinking of the A9 is some sort of irritating for the eyes. My mind always says there must be something wrong.

I would suggest to change the behaviour to a solid light when a connection is established. Hope this is changeable with a firmware update if considered.

Thanks for listening.
