LPC-2148 USB Isochronous Examples based on lpcusb

Today I read an interesting article from Linux Journal.
http://www.linuxjournal.com/article/10421

In the article, there is an interesting example of Isochrouns USB Transfer example based on lpcusb. So I use lpc21isp and download the code to my Olimex LPC-P2148 board which the developers are also using. They have also the Linux host example based on usbfs which seems to work right out of the box. Now I need to read the firmware in more detail.

There are also quite some examples from the psas site.

libusb related wrappers or bindings

Most of the following libusb wrapper/binding work with both libusb and libusb-win32 0.1 version. As far as I know, there are no libusb wrapper/bindings yet for the new libusb-1.0 (currently only Linux and Mac OS X) or Openusb (currently only Linux and Solaris).
