+# Changes 📝
+
+## 🆕 New Features
+- Introduces support for reading common Human Interface Devices (HIDs) like USB mice and keyboards
+- Implements a number of example sketches to illustrate how to successfully interface with USB HIDs
+
+## ⚠️ Known Issues
+- Compatibility with advanced mice and keyboards (offering multimedia buttons and visual effects) is limited or unknown
+- Reading the scroll wheel input from mice is not supported with this initial release
+- Only allows for connecting one keyboard and mouse
+
+Please refer to the [Arduino Docs Website](https://docs.arduino.cc) for detailed information on these changes and how to use the new features.

- * In order to use two (or more) HID devices connected via a USB hub to your Portenta C33 board, please open "tusb_config.h" below (right click -> Go To Definition)
- * and make sure that "CFG_TUH_HUB" is set to value 1, and that "CFG_TUH_HID" is set to the number of HID devices you intend to connect to your Arduino (2 in this example).
