A go library to communicate via a the ANT usb stick.

You need permission to read and write the USB device. To do so add a text file with the following to /etc/udev/rules.d/99-garmin.rules

On Ubuntu 10.04 (or lower):

SUBSYSTEM=="usb", SYSFS{idVendor}=="0fcf", SYSFS{idProduct}=="1008", MODE="666"

On Ubuntu 12.04 (or other distros running newer udev):

SUBSYSTEM=="usb", ATTR{idVendor}=="0fcf", ATTR{idProduct}=="1008", MODE="666"

Mac requires libusb to be installed from source code. Make sure you have XCode, Mac OSX SDK and the command line tools installed and run:

brew install libusb --HEAD

Now when you build the project you can get the following error:

# github.com/kylelemons/gousb/usb
iso.go:67:8: struct size calculation error off=72 bytesize=64

Joseph Poirier proposed a quick fix that should work:

Just wondering if anyone has looked into this since the last post? I tried to compile Kyle's gousb package on OSX today but ran into this problem; the quick hack was to change the struct's flexible member size to 1 in libusb.h.

You can find libusb.h in /usr/local/include/libusb-1.0/libusb.h. Here is a gist of my modified libusb.h. The change has been made at line 937.
