I do not use it in product but the Stack 2.4 works fine with my Explorer 16bit demo board+ USB PICtail+ board + PIC24FJ256GB110 USB PIM combination. There are some minor bugs in the stack and some missing features. Are you going to use the host mode or the device mode? I have not testing too much on the host side. I know the USB composite based keyboard (those multimedia keyboard) is not supported. >From the errata, there are several problems with the USB module. It depends on your application whether they will affect you or not. As long as you can live with the workaround, that should be ok. -- = Xiaofan http://mcuee.blogspot.com -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
