HI, guys

I made custom board with LPC1549. the USB-ISP works as expected in this hardware.However, when the USB-CDC sample run, Windows doesn't recognize it.

I added LED blink code using  SysTick to this sample, and I make sure runing this code. So LPC1549 was not hang.

I tried sample of USBDevice for Mbed. it code run without problem. so i think that hardware doesn'd have problem.

Does anyone have any ideas on what I can try?
