As Clemens wrote, examining existing drivers in the kernel repository (under sound/usb) might help you most. Just have a look how they communicate with the hardware and how they set up the ALSA components inside the kernel. Is there any documentation for the chip you're writing the driver for, about the USB protocol it uses etc? Are you sure it does not follow the USB audio class specifications? Posting the output of 'lsusb -v' might also help.
