It is interesting that there is no detailed info from Altera about UB3! The Agilex5 modular devkit already uses UB3 as can be seen from public documentation. So UB3 is coming, soon? Well the modular kit user guide does not explain how to enable UB3 it says connect Intel Download Cable II to 10 pin header
