GR uses interface 1 for TX, and interface 2 for RX. For some reason,
LIBUSB finds that interface 1 is null, and thus not usable. Hence
the error.
You can get to the file in question via DarwinPorts:
port configure libusb
cd `port dir libusb`/work/libusb-0.1.12/
then the file that needs changing is "darwin.c". I haven't had time
to look through the details yet, to see what's changed on Darwin for
Intel (for MacBook and Pro models only) and thus what needs to be
changed for LIBUSB. Might be simple, might not. More as it
comes ;-) - MLD
