There are USB controller chips that do NOT depend on
the PCI bus. Someone on the Vintage Macs list
found one that requires very little in the way of
extra stuff. That would make the hardware end of
USB for older Macs fairly easy for someone who knows
olde Mac hardware very well and can build computer
stuff from "scratch". The really nasty bit would be
writing the USB drivers, especially for 68k systems.

It may be possible for a talented hacker to make the
PCI PowerMac USB drivers work on a NuBus PowerMac.

The big iffy point is whether or not USB extentions
for 3rd party devices would work without modification?
Maybe not on NuBus PowerMacs, very likely on 68k.

USB for a Duo would most likely have to be on a
NuBus card in a Dock.
