Using CMSIS-DAP v2 removes the necessity to install separate drivers on Mac OS, Linux, and Windows (8 and above) for the debug adapter.

Additional requirements for Linux

On Linux, permission to access USB devices from user space must be explicitly granted via udev rules. Exemplary udev rules are available in the pyOCD GitHub repo that allow to access common debug probes without requiring it to be run as root.

Additional requirements for Windows 7

For Windows 7, the CMSIS-DAP v2 device will install automatically if the PC is connected to the Internet and device installation settings are set to automatically download and install drivers for devices. The installed device will be seen in the Device Manager under Universal Serial Bus devices as a WinUSB Device.

If no Internet connection is available or you want the device to show with a different name in the Device Manager, you should provide an .inf file. Refer to USB Driver and *.inf file for more information.
