- atrf/fw/include/atspi/ep0.h enum atspi_requests), atrf/fw/atspi/ep0.c
  (my_setup): new command ATSPI_POLL_INT to poll IRQ_RF
- atrf/fw/atspi/ep0.c (my_setup): ATSPI_BUILD sent one byte too many
- tools/lib/atusb.c (atusd_interrupt, atusb_driver): implemented interrupt
  polling
- tools/lib/atusd.c: added section title for the RF interrupt function
