current revision which i think is r958 has same problem, but it is not a 'stable' release version so i think you will have to wait for them to update it.
i was using r956 which didn't have this issue, seems the timeout period (15sec i think is current) is not long enough to detect the usb device, although it worked fine in r956, and works fine in other loaders.

i think they 'just' recently started working on it again, But i think the .dol / .wad files for it won't be available till it's more stable.
