Missing USB IDs for M-Audio Micro

Hello!

I have an M-Audio Micro USB soundcard, which works great, though I have 
to manually add the USB IDs to snd-usb-audio when I want to use it.

echo 0763 201a > /sys/module/snd_usb_audio/drivers/usb\:snd-usb-audio/new_id

I was hoping you could add the IDs somewhere in the driver to enable it 
by default, since the output, input and even bass boost "feature" seem 
to work just fine.

Below is the lsusb information for this device.

Thanks!
Ash
