Hope is UK, SRAM is ROC, Shimano May Be too, perhaps Jpn.

I have 2 Schmidt dyno-hubs, with disc mounts, one is 6 bolt,
the other centerloc.
I have an adaptor to use 6 bolt discs.
I run my lights off them.. there are pieces made to tap USB power
off them to keep your mobile phone, etc. juiced.

Shimano has one too, in the Alfine group.

minus the power

add to list: Phil Wood and Chris King and White industries
they are Made here on the west coast.
