The USB 2.0 and USB 3.0 protocols are backwards compatible with USB Type-C. However, because the USB Type-C plug or port is different in form, you might need to buy compatible adapters to connect your older devices to a USB Type-C port. RND provides USB Cables with USB-C plugs to USB-A plugs or USB-A sockets. Have a look at the RND webshop to find the right cable.
