I am new to EZUSB. I have a FX2 chip, that I am trying to enumerate as a HID device. Before I start with the USB enumeration, can some one tell me what registers have to be initialized in the 8051? I was thinking - IE0 (enable global interrupt), IP(not sure). I am not using any timers at the moment, so I don't have to initialize any timer registers. Any USB registers need initializing?
