Does Viltrox EF-M2 on BMCC work?

Does anyone have any experience with the Viltrox EF-M2 on BMCC 2.5 ?
I know it will only work for manual lenses, and that's fine.

Not for me. Aperture works kind of properly.
IS and AF does not work completly.
I have tried combinations of defferent lenses(some are compatible with viltrox, and some are not), and cameras (BMPCC4K, GH5, Canon 80D and Canon 5DSR) - it looks that conection betwen BMPCC and Viltrox fails.

I'm talking the BMCC which has a passive MFT mount as it is.

I just tested the viltrox ef m2 with the BMCC 2.5k MFT and it works (optically) but I couldn't adjust iris.

I tried with a tokina 11-16mm DX (and I couldn't infinite focus even after adjusting the focal reducer on the viltrox (I've read it only works with the DXII newer version of the lens), I tried with a zeiss 50mm 1.4 ZE, no iris control. I even tried powering the adapter thourgh the miscro usb port with a 5V battery (since the mft mount on the BMCC is passive, there fore it can't power the stabilization and iris natively) and it DIDN'T WORK.

I used firmware 3.4.

How old are your BMCCs guys? And how its holding up?
I had 2, one still with me and both presented problems.
