The WMR100/200 use a proprietary protocol for their USB connection. It's very useful for enthusiasts running a headless Linux box to collect and analyze data from this link, but unfortunately the protocol isn't openly documented, nor are clients provided for this platform.
This simple C program handles the USB protocol of the WMR100, and translates it an ASCII line-format, easy for parsing/analysing.
You'll need to setup the udev rules (see udev/README) if you want to run this not as root. This is due to how libhid accesses the USB ports.
libhid-dev (or similarly named) package installed. pkg-config package installed.
Run 'make'.
To install, copy wmr100 to your path.
One time install for osx
To keep the default HIDManager from taking the wmr100, run this once: make setup_osx
If you want to use different software to read the wmr100 device, you should undo this by running
make unsetup_osx and then reboot so that the HIDManager will take control of the device again.
I'd suggest you run ./wmr100, which will dump data to data.log as well as stdout. You can then process periodically data.log with a script in python/perl/ruby/your language of choice, and frob with the data that way.
Alternativally you could adapt the original C code to write to a database directly instead, but that's more pain that I'm willing to endure. :-)
