MR816 CSX/X Firmware V1.10 install issues

Hello

I have installed the firmware update V1.10 a number of times step by step but…
Boot, Main and IEEE1394 stay V1.00

I have a MacBook Pro with Mojave .
The only thing that I can not do in the instructions is to connect firewire directly to the MacBook. I have to use a hub.
Will this prevent the firmware from updating?

Thanks
Tom
