# BTstack Port for Windows Systems using the WinUSB Driver
Although libusb basically works with the POSIX Run Loop on Windows, we recommend to use the Windows-WinUSB port that uses the native run loop and WinUSB API to access a USB Bluetooth dongle.
To allow libusb or WinUSB to access an USB Bluetooth dongle, you need to install a special device driver to make it accessible to user space processes.
It works like this:
- Start [Zadig](http://zadig.akeo.ie)
- Select Options -> “List all devices”
- Select USB Bluetooth dongle in the big pull down list
- Select WinUSB (libusb) in the right pull pull down list
- Select “Replace Driver”
When running the examples in the MSYS2 shell, the console input (via btstack_stdin_support) doesn't work. It works in the older MSYS and also the regular CMD.exe environment. Another option is to install WinPTY and then start the example via WinPTY like this:
$ winpty ./hfp_hf_demo.exe
