In the full speed section of a FX2LP device descriptor file, is it OK to set BULk EP's max size to 512, does it hurt anything?. In the high speed section it definitely must be set to 512. Does it cause problem if the max packet size is set to 512 bytes not 64 bytes in the full speed section for a bulk endpoint?.

Also, is there an example that shows in a FX3 device how a (gpio) pin is used to handle external interrupts for buffering the incoming data, etc?. Any example of ring buffer or mailbox that is used for the buffering of incoming data available?.
