+ * \brief BeRTOS Virtual USB Mouse.
+ *
+ * This project implements a HID USB device using the Olimex STM32-P103
+ * evaluation board. The virtual mouse can be connected to the USB port of a
+ * normal PC.
+ *
+ * The WAKE_UP button on the board can be pressed to send to the host the mouse
+ * movement to draw a rectangle shape (taking the left button pressed).
+ *
+ * Example (mouse detection on Linux):
+ *
+ * $ dmesg | tail
+ * [25361.710435] usb 1-8.1.3: new full speed USB device using ehci_hcd and address 33
+ * [25361.943901] usb 1-8.1.3: configuration #1 chosen from 1 choice
+ * [25362.004002] input: BeRTOS USB Mouse as /devices/pci0000:00/0000:00:1d.7/usb1/1-8/1-8.1/1-8.1.3/1-8.1.3:1.0/input/input19
+ * [25362.004738] generic-usb 0003:FFFF:0000.0008: input,hidraw3: USB HID v1.10 Mouse [BeRTOS USB Mouse] on usb-0000:00:1d.7-8.1.3/input0
