This patch adds support for the Garmin USB2 stick using
libusb-win library. Instructions are included in gcconfig.pri.in
for configuring and installing the neccessary libs.
To enable support for USB1 and USB2 support in the same binary
stubs are created when UsbXpress/Libusb are not available and the
device i/o attempts to use USB2 before falling back to USB1.
Since I was also in the middle of some coding changes I merged
my developments (Mark) with Darren's patch whilst fixing it up
for commit, namely:
1. the configuration screen no longer demands a COMx port
when using Native ANT+ on Windows.
2. new signals in ANTChannel notify the ANT class when info is
stale or lost (but they are not used at present).
3. The previous debug messages have been removed, although new
debug messages are added for stale/drop/timeout signals.
This patch provides support for Garmin USB1 sticks under
Windows. Since the device does not present a serial port
this code uses the USBXpress API from SiLabs that the
Garmin device uses.
Support for USB2 sticks is pending.
To build you will need to download and install the SiLabs
development kit from http://www.silabs.com/products/mcu/Pages/USBXpress.aspx
and set USBXPRESS_INSTALL appropriately in gcconfig.pri. I
have provided instructions in gcconfig.pri.in.
At runtime the SiUSBXp.dll will need to be in the path, I will
assume that Gareth will fix up the windows installer for this, but
for now just copy the file manually.
Tested with a GARMIN USB1 stick on Windows 7 with SRM, Garmin HR and
a GSC-10 dual speed/cadence device.
There are other minor fixes to the ANTMessage code in this patch
related to decoding of calibration messages.
