because the old hiddev is still there, and will only be removed for 2.2.
as previously, nut as always a migration path, no rude switch

you can try "export USB_DEBUG=3" to trace libusb internal routines.
what is sure is that it's not a permissions problem (you're running it
as root), so I'm more thinking about either a device problem, or the
driver not supporting it. But once more, I don't have the needed
knowledges on this subject.
