Hi Jorg,
I havent implemented this core, but I can answer your question in a limited 
way.
The project you have planned is very much possible using USB2.0. For the 
driver, you can use built-in USB audio class HID drivers provided in windows 
itself. You just have to report the descriptors appropriately from hardware.
A suitable audio codec can be used to interface your digital data to be 
converted to analog and output to a speaker. The philips 1341 is a good 
stereo audio codec. You might have to develop its interfacing logic within 
your Spartan.

Hope this helps,

Regards

Rohit

Subject: [usb] USB Bandwidth & Driver

Hi,

I just found this USB project on opencores
and I got some important questions.

- Has anyone implemented this core on a Spartan II
   (I use the development board for now) and made
   bandwidth-messuring for "real-life" application?
   (I plan to read/write 8 Channel of Audio 24Bit@96Khz)
   Would this be possible?
- Is there a starting point for programming a windows
   device driver for the USB part? Has anyone already
   developed one, is there maybe source-code for it
   or can someone at least give me ideas what I
   have to consider.
- Can I find the scematics how to connect to the PHY
   somewhere?

Thanks, Jörg.
