to surpress ground current just turn the usb cable a few turns around a ferrite core (bigger donut shape)
that should work well enough

USB 2.0 is hard to do over fiber, thanks to it beimg pseudo differential.
So both ends of the fiber need smarts for it to work.
Onlybreally seen those Analog Devices made USB isolators on the market and
they are for electrical safety/galvanic isolation and sometimes can
imtroduce noise on their own.
