I have a USB audio device which is recognized correctly on my Fedora system (Fedora-20 with all updates running KDE) but is not recognized by another Linux system (a Samsung Chromebook).  Can anyone tell me how Fedora recognizes the device, so I can figure out whether it would be practical to tweak the Chromebook to get it to recognize the device.  The device shows up this way:
$ lsusb
...
Bus 005 Device 003: ID 08bb:2702 Texas Instruments Speakers
...
and appears in my alsa configuration as:
$ aplay -l
...
card 1: PCM2702 [Burr-Brown Japan PCM2702], device 0: USB Audio [USB Audio]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
...
Any info/hints/links/etc would be much appreciated.
