No, uhci doesn't use hints (in theory, however, it wouldn't be difficult to add support for "hints.uhci.X.disabled", I think). Most of the device hints can only be used for legacy (non-PnP) ISA devices. > I'm not sure which of those controllers I might actually need and it > might be none of them.

Just look at dmesg or the output from "usbdevs -v". You should be able to see to which controller the ums/ukbd of your remote console are connected.
