Can I use Cerbo GX 2.57 USB ports for powering a USB hub?

I am currently using firmware 2.54 and using all USB ports for MPPT controllers. I understand 2.57 will make one of the USB ports power-only.

I have a USB hub that can be powered from a USB port. Does the power-only port provide enough power to connect the hub and then use the HUB to connect two of the MPPT controllers to it?

It may work, but it would not be recommended - that port is now reserved for powering the GX touch display, and anything else should be considered unsupported.

Could you not use one of the other ports?

Cerbo -> USB1 - USB Hub data -----|---> MPPT 1
                     ^            |---> MPPT 2
                     |            |---> MPPT 3
      -> USB2 - USB Hub power

      -> USB3 - not used/GX touch display USB



Also I presume that there is a reason you are not just using the VE.Direct ports for the MPPTs?
