USB 2.0  is up to 480 Mbit/sec

CD quality audio is 44.1 ksample/sec at 16 bits x 2 channels = 1.4 Mbit/s.

So you're fine as long as you don't use a USB 1.0 port!

I am not a professional audio engineer, but to me, the Behringer DAC 
sounds as good as a CD player using decent (£500-quality) equipment.
