In hids_init() function there is a the hid report descriptor that defines the content of the hid reports. For the mouse report sent in your code this is the relevant section.

      // Report ID 1: Mouse buttons + scroll/pan
    0x85, 0x01,       //     Report Id 1
    0x09, 0x01,       //     Usage (Pointer)
    0xA1, 0x00,       //     Collection (Physical)
    0x95, 0x05,       //         Report Count (5)
    0x75, 0x01,       //         Report Size (1)
    0x05, 0x09,       //         Usage Page (Buttons)
    0x19, 0x01,       //             Usage Minimum (01)
    0x29, 0x05,       //             Usage Maximum (05)
    0x15, 0x00,       //             Logical Minimum (0)
    0x25, 0x01,       //             Logical Maximum (1)
    0x81, 0x02,       //             Input (Data, Variable, Absolute)
    0x95, 0x01,       //             Report Count (1)
    0x75, 0x03,       //             Report Size (3)
    0x81, 0x01,       //             Input (Constant) for padding
    0x75, 0x08,       //         Report Size (8)
    0x95, 0x01,       //         Report Count (1)
    0x05, 0x01,       //         Usage Page (Generic Desktop)
    0x09, 0x38,       //             Usage (Wheel)
    0x15, 0x81,       //             Logical Minimum (-127)
    0x25, 0x7F,       //             Logical Maximum (127)
    0x81, 0x06,       //             Input (Data, Variable, Relative)
    0x05, 0x0C,       //         Usage Page (Consumer)
    0x0A, 0x38, 0x02, //             Usage (AC Pan)
    0x95, 0x01,       //             Report Count (1)
    0x81, 0x06,       //             Input (Data,Value,Relative,Bit Field)
    0xC0,             //     End Collection (Physical)

This might look a bit cryptic, but basically says that five first bits in the first byte corresponds to button 1 to button 5 on a standard HID mouse. Button 1 is left button, Button 2 is right button, Button 3 is center button and button 4 and 5 are typically the "back" and "forward" buttons you find on the sides of a mouse.

Second byte is for the scrollwheel. It takes values from -127 to 127

Third byte is for panning. Takes same valus as the scrollwhell I believe.

To send a "right button" press you must set the second bit in the first byte to '1' before sending it. You must always send all three bytes.

The report would then have the value {1, 0, 0} for left button. {2,0,0} for right button. {4,0,0} for center button. Both left and right would be {3,0,0}.

case BSP_EVENT_KEY_0: mouse_click_send(); break;

Is this in an event handler ?
