At least at the moment we don't have support for standalone (USB and
bluetooth) GPS devices. I had a long discussion about this with the
last maintainer of geoclue1, Bastien Nocera. He informed me that main
issue with these devices is that they are not plug-n-play and we'd
need user intervention to set them up and geoclue is aimed for
simplicity. Having said that, I won't be against anyone attempting to
add this support.

You might find this recent discussion interesting if you want to
utilize your phone's GPS:

This is likely because support for this is either not present or not
complete in ModemManager. Please file a bug on ModemManager about
this.

You can run geoclue manually with debug enabled (export
G_MESSAGES_DEBUG=Geoclue) and it'll tell you everything its doing.
