A custom HTC One X interworks with a USB headset:

"It appears that my HTC One X running Android Revolution HD 13.0 (Jelly Bean) has the drivers and loaded modules for snd_usb_audio. And when I plug my USB DAC into it. It recognizes it and automatically directs sound to it. This is good.
I've dived into why it works on the HTC One X and not on my Xoom and come across a folder called /proc/asound
This folder is to do with the ALSA (Advanced Linux Sound Architecture) and when I plug my USB DAC into my One X, it creates a folder called 'Headset' (since my USB DAC is a headset).
I've found folders named "snd_usb_audio" (or similar) in the following folder locations:
/sys/bus/usb/drivers/snd-usb-audio
/sys/module/snd_usb_audio"
