- usbwait/usbwait.c: update the USB device tree until the specified
device is detected
- usbwait/Makefile: build usbwait (host only)
- Makefile (DIRS, BEN_DIRS, upload): separated subdirectories with tools
that can run on the Ben from those that can't
- Makefile (DIRS): added usbwait/
- usbopen.c (open_usb): determine vendor and product objective outside
the loop
- usbopen.c (open_usb): check vendor and product only if non-zero
- usbopen.c (bad_id, parse_usb_id): vendor and product can now be
omitted
- tools/include/usbopen.h (usb_rescan), tools/lib/usbopen.c (initialized,
initialize, usb_rescan): usb_rescan forces a re-initialization of
libusb and a new scan of the USB device tree
- usb/usb.h (USB_LANGID_ENGLISH_US): added USB LANGID for US-English
- board.h (board_sernum), board.c (board_sernum, hex, get_sernum,
board_init): provide the board's serial number in "board_sernum"
(UTF-encoded)
- sernum.h (sernum_get_descr), sernum.c (sernum_get_descr): return
string descriptors for the serial number
- descr.c (device_descriptor), usb/dfu.c (device_descriptor):
set iSerialNumber if serial number is available
- atusb.c (main), usb/dfu.c (my_descr): call sernum_get_descr for
unknown descriptors
- Makefile (OBJS, BOOT_OBJS): added sernum.o
What caused the error that looked like a problem with the functional
descriptor was in fact the boot loader resetting between the bus scan
and retrieval of the descriptor.
- board.c (board_init): disable the watchdog timer (tricky !)
- board.h (reset_cpu), board.c: enable the watchdog timer to cause a
CPU reset
- ep0.c (my_setup): uncommented and updated ATUSB_RESET handler
We currently don't provide the DFU Functional Descriptor, which modern
versions of dfu-util request to determine the transfer size. Luckily,
they don't do this if the transfer size is given on the command line.

(N_CHAN): declare number of channels in one central place instead of
scattering it all around the program

number of sweeps
The transceiver reset takes quite a while. It seems that also going into
sleep mode has the effect of stopping cw test mode and it's much faster.
This has only been tried on the AT86RF231. For AT86RF230, we therefore
still use the reset.
Performance improvement:
Measurement: atrf-path sweep time in GUI mode, averaging over 10 samples.
Running on PC with remote ATBEN transceivers.
