I need to implement usb hid for my current project.So i thought of trying some code that works and use it as a base to form my code for usb. I am using NGX BLUEBOARD LPC2148 as my development board. Flashed LPCUSB by Bertrik Sikken and the board gets enumerated. But the code is not interrupt driven. So I tried KEIL example code for HID but the board never gets enumerated.Could someone guide me on this issue.
