First of all, using LPC2138 for USB applications is not a good idea. Why don't you use LPC214x? You have very good USB audio example on keil page: http://www.keil.com/download/docs/308.asp <quote> An USB Audio Device (HID) does not require any special USB driver, since the USB Audio support is already built into Windows 2000 and Windows XP. Therefore USB Audio devices can be directly connected to the computer. </quote> Girish Wabale wrote:
