I am using a7c + ronin rsc2 +reveneye.
Everything in reveneye works fine. But it doesn't charge. So if I plug it into the middle usb-c port of the ronin rsc2, it charges, but active tracking doesn't work.

This is a big problem when shooting.

Why can't operation and charging work at the same time?

You said that the active tracking and charging  cannot be used at the same time. This is unlikely. The active tracking will not be affected during charging
