NXP(原飞利浦)的LPC214X系列ARM上的USB在系统升级的源代码,极力推荐!!开发者主页: http://www.simonqian.com/en/LPCUSBBoot/

v20070727
	20070623, bertrik
	* target/usbhw_lpc.c: Updated function descriptions, Removed setting of direction of Vbus pin (P0.23)

	* target/usbhw_lpc.c: Updated interrupt handling order to first FRAME, then DEV_STATE, then EP_SLOW.
	* target/examples/main_serial.c: Reduced interrupt-flood in main_serial.c by disabling the bulk-in NAK interrupt
	  when no more data is available and enabling it again at the start of a new frame.
