Thank you for asking!  As Danijel 
mentioned  USB Audio 2.0 support is important for higher sample 
rate / higher bit-depth / higher channel count hardware.  If the hardware 
does 24-bit 192kHz then USB Audio 1.0 cannot even do 2 channels.  Even with 

the more widely used 24-bit 96kHz, then channel count is limited to 
stereo.  If someone wants to just use 24-bit 96kHz for 5.1 playback, this 
simply isn't possible with USB Audio 1.0.   
Now that there are more USB Audio 2.0 solutions coming to 
market, each company is having to develop it's own driver... and of course 
will have varying degrees of success.  Audio driver development is 
generally not the core competence for a chip-set company so they end up 
having a 
3rd party company develop the driver.  OEMs end up with the "not our fault" 

situation where the chip-set company blames the driver company and the 
company isn't being paid to fix bugs.  The end result is products that 
don't work very well on Windows but work better on OS X. 
As it is now, all of the USB Audio 2.0 solutions are having 
to be qualified on OS X 10.6 (which does support USB Audio 
I think the key issue is market acceptance.  
Microsoft never supported audio on FireWire in the OS, and I would say 
there are 
fewer FireWire audio devices on the market as a result. If Microsoft 
USB Audio 2.0 in Windows 7 SP1, I think you will see many USB Audio 2.0 
hit the market. 
Thank you,

  There are occasional questions 
  on this list about USB Audio 2.0 support in Windows. We (the Windows 
  team) are curious to hear specific reasons- scenarios, business, 
  etc.- that would be enabled if USB Audio 2.0 support was included in 
  Are any of you willing to 
  share this? The more specific you can be, the better. If you do not want 
  share with the entire list then feel free to send a message to me
