### Windows

From the [official manual](https://m-labs.hk/artiq/manual/installing.html#configuring-openocd):

On Windows, a third-party tool, Zadig, is necessary. Use it as follows:
1. Make sure the FPGA board’s JTAG USB port is connected to your computer.
2. Activate Options → List All Devices.
3. Select the “Digilent Adept USB Device (Interface 0)” or “FTDI Quad-RS232 HS” (or similar) device from the drop-down list.
4. Select WinUSB from the spinner list.
5. Click “Install Driver” or “Replace Driver”.
6. After above steps done, you may see the devices in the Device Manager:

You may need to repeat these steps every time you plug the FPGA board into a port where it has not been plugged into previously on the same system.
