Code

atusb/fw/: added reporting of RF interrupts via bulk EP1

Browse Source 
- board.h (board_app_init), board_app.c (board_app_init): new function
  for application-specific board initialization
- atusb.c (main): call board_app_init
- board_app.c (INT0_vect): on RF interrupt, read REG_IRQ_STATUS and
  send the status byte on EP1
- board_app.c (board_app_init): set up interrupt on rising edge of
  INT0 (INT_RF)
- descr.c (config_descriptor): added EP1 as bulk IN
