    Genius Gila Gaming Mouse presents an obviously wrong report descriptor.
    the Consumer control (report ID 3) is the following:
    0x05, 0x0c,                    // Usage Page (Consumer Devices)       105
    0x09, 0x01,                    // Usage (Consumer Control)            107
    0xa1, 0x01,                    // Collection (Application)            109
    0x85, 0x03,                    //   Report ID (3)                     111
    0x19, 0x00,                    //   Usage Minimum (0)                 113
    0x2a, 0xff, 0x7f,              //   Usage Maximum (32767)             115
    0x15, 0x00,                    //   Logical Minimum (0)               118
    0x26, 0xff, 0x7f,              //   Logical Maximum (32767)           120
    0x75, 0x10,                    //   Report Size (16)                  123
    0x95, 0x03,                    //   Report Count (3)                  125
    0x81, 0x00,                    //   Input (Data,Arr,Abs)              127
    0x75, 0x08,                    //   Report Size (8)                   129
    0x95, 0x01,                    //   Report Count (1)                  131
    0x81, 0x01,                    //   Input (Cnst,Arr,Abs)              133
    0xc0,                          // End Collection                      135
    
    So the first input whithin this report has a count of 3 but a usage range
    of 32768. So this value is obviously wrong as it should not be greater than
    the report count.
