for "usb-c" u may not find anything at all
c is atm more or less for smartphones or so
for usb A (usual PC usb port) u can find plenty, u can still use adapters on it to convert C to A ports (or vice versa), so u can use themon 2 or more computers
so ull be able to use single usb hub with tons of usb devices connected to it hooked up to many computers, BUT only 1 PC can access those usb devices at a time (ull be able to switch between computers - manualy (button(s)))
is that what u want?
if u want to use your usb devices on 2+ computers at same time, then there is no such thing
