I have the same output with the Maya USB. It's all right with that:
usb 2-1: USB disconnect, address 4
usb 2-1: new full speed USB device using ohci_hcd and address 5
HID device not claimed by input or hiddev
Can you try:
# cat /dev/urandom > /dev/dsp
(Turn down the volume of your speakers and abort with Ctrl+C very quickly)
This should produce a white noise completly independent from alsa. If
you hear the noise you can be shure that there's all right on the device
layer.

Well, tried it and I got sound coming from my laptop speakers so I
suppose /dev/dsp is used by my laptop's integrated soundcard.
I also have a /dev/dsp1. I tried redirecting urandom to it and got this:
cat /dev/urandom > dsp1
cat: write error: Broken pipe
/dev/dsp and /dev/dsp1 area actually symbolic links to /dev/sound/dsp
and /dev/sound/dsp1, respectively.
Here are the contents of my /dev/sound directory:
