When I was working on v3, it was based on

    d202f67db077 Merge branch '2020-04-25-master-imports'

And it was definitely working. My Rock64 is back in its case, so I tested
again with the ROC-RK3328-CC just now. All three USB ports work properly,
on both the old tree and current master.

Are you using the defconfig, or have you deviated from it? XHCI must be
enabled, as VBUS is tied to it (to get everything to work).
