Flashing an SDCard with the ROM provided by Canaan fixed the VidToo Controller and I am going to replace my RP3 with VidToo especially because I had some issues with one of the AUCs keep disconnecting randomly to see if this fixes the problem. Tried multiple 2.5a and 3a power adapters and no success.

A good thing about the VidToo controller I believe is that it doesn't use a USB Hub (need to double check it to be sure, but the processor used has 4 separate USB duel pins), but RP3B uses a USB Hub internally shared by the ethernet controller and all 4 full sized USB ports; so that might be the reason for my problem. Or maybe 1200ma (max supported USB current in RP3B) is not enough for 3 AUC and I need a powered USB Hub.

As for OrangePi, unfortunately, my OrangePi One didn't boot up with the ROM provided by the Cannan for H2-H3 even tho they are similar. You can still install the OpenWRT and then install the necessary packages manually. But the release ROM is not compatible out of the box.
