Did you hold down input 1 source select when you started the device?  The
quick start guide indicates that will force the device into full speed
mode (i.e. 12Mb/s USB 1 speed rather than 480Mb/s USB 2 high speed).

The Sound Devices information seems out of date, the documentation
indicates that linux will only support full speed mode, but I think that
is not correct.  If you held down input 1 select when powering on to force
full speed mode, do not do that, let the device initialize in high speed
mode.  Linux USB driver has supported USB 2 audio class and high speed
mode for quite a long time.
