/** Event for USB mode pin level change. This event fires when the USB interface is set to dual role
* mode, and the UID pin level has changed to indicate a new mode (device or host). This event fires
* before the mode is switched to the newly indicated mode but after the \ref EVENT_USB_Device_Disconnect
- * event has fired (if connected before the role change).
+ * event has fired (if disconnected before the role change).
*
* \note This event only exists on microcontrollers that support dual role USB modes.
* \n\n
* This event is time-critical; exceeding OS-specific delays within this event handler (typically of around
* two seconds) will prevent the device from enumerating correctly.
*
- * \note For the smaller series 2 USB AVRs with limited USB controllers, VBUS is not available to the USB controller.
+ * \note For the microcontrollers with limited USB controller functionality, VBUS sensing is not available.
* this means that the current connection state is derived from the bus suspension and wake up events by default,
* which is not always accurate (host may suspend the bus while still connected). If the actual connection state
* needs to be determined, VBUS should be routed to an external pin, and the auto-detect behaviour turned off by
