- 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
- usbopen.h (usb_unrestrict), usbusb.c (usb_unrestrict): drop ID and
path restrictions
- atusb.c (atusb_open): call usb_unrestrict to remove restrictions
Examples:
usb:1/6 select logical device 6 on bus 1
usb:1-3.1.4 starting at bus 1, choose ports 3, 1, and 4
- usbopen.c (initialize, open_usb): moved libusb initialization to
separate function, to allow for sharing
- usbopen.h (restrict_usb_path), usbopen.c (restricted_path, open_usb,
restrict_usb_dev, restrict_usb_by_dev, read_num, restrict_usb_by_port,
restrict_usb_path): added mechanism to restrict USB path
- atusb.c (atusb_open): if an argument is given, call restrict_usb_path
with it
We shared it across projects so far, but since the code will be further
customized, it's better to keep it local (at least for a while).
- usbopen.h, usbopen.c: moved over f32xbase/include/usb.h and
f32xbase/lib/usb.c (for further customization)
- Makefile (CFLAGS, OBJS_host): use usbopen.o instead of usb.o from
f32xbase
- atusb.c: use usbopen.h instead of usb.h from f32xbase (also removes
include path ambiguity)
