Here is the device string I use in Guayadeque
plughw:CARD=DragonFly,DEV=0
When I say "does not work properly" I mean that 44.1/16 plays fine but higher rates don't - I get nasty static buzzing instead of music.
I don't know why this is, but I spent a long time trying to figure out what was "wrong" with my configuration, the kernel, the Alsa driver, etc etc when I finally in desperation plugged the card into one of the other USB ports and POOF all worked fine.
Beyond that, I have a completely vanilla configuration (no messing with Alsa configuration files). I continue to let Pulse Audio live on my system, and the default sound card is the Intel stuff delivered with the machine. So all alerts and system audio go through that subsystem, and only Guayadeque uses the Dragonfly.
