If the device is class compliant (aka does not require a driver to be
installed on OSX or Windows) then it's very easy.  Otherwise it's very
hard without detailed hardware specs.

Sometimes.  They've helped with the EMU1212 series and CA0106 (SBLive!
24 bit) but won't help with the X-Fi.

Read "Writing an ALSA driver" and refer to the source code of existing
drivers such as snd-usb-audio.
