OpenXC Vehicle Interface Windows Driver

This is a Windows driver for an OpenXC vehicle interface attached via USB. You must install this driver to send and receive data through the VI from Windows (including Cygwin). The driver is compatible with 32-bit and 64-bit Windows 7, Vista and XP.

After downloading the driver files, plug the VI into your computer via USB. Windows will search for a driver but will be unable to find one - you have to manually browse to the folder where you downloaded this driver.

2. Locate a device with a yellow question mark next to its icon. Assuming you have no other USB devices with no assigned drivers, this will be your OpenXC module. Right-click this device and click "Update Driver Software..."
3. Click "Browse my computer for driver software"
4. Click "Let me pick from a list of devices drivers on my computer"
5. Click the "Have Disk..." button, then click "Browse..."

Testing

You can test that the driver is properly installed by using the OpenXC Python library. Follow the instructions on the python OpenXC site to install the library, then run the "openxc-version" command. It should report back which car firmware you have flashed onto the VI (Or report no firmware installed if you haven't flashed a firmware yet).

If you're still getting errors about USB not being found/installed, restart your computer, and if the issue persists, come ask for help in the Google Group.
