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
• 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
