Just wanted to say that I'm looking to try SqueezeOnArch and have a
similar problem with what you're encountering.  My current setup is as
follows:

Cubox-i4pro LE (1.2ghz)
Volumio 1.55
Dragonfly 1.0 (with Dragontail extender)

When I connect the Dragonfly to the Cubox directly, I get pop/crackles
when playing 16/44 material.  Playing 24/96 was ok.  I used a Belkin
powered hub between the two and everything works perfectly now.  I got a
reply from Gordon Rankin saying that since the USB controller (TAS1020B)
is full speed and not high speed, maybe somehow the hub is
"re-packetizing" things.  

Anyway, it looks like using the hub is the only way to go right now as
I'm still waiting for my XMOS powered DAC (LH Labs Pulse X Infinity). 
I'm hoping that it's plug and play with the XMOS controller since the
DAC isn't USB powered.
