+ * @brief HyperX Cloud II Wireless Gaming Headset (Kingston-branded revision)
+ *
+ * Uses a different protocol than the HP-branded version (0x03f0:0x0696).
+ * Protocol reverse-engineered from HyperHeadset project:
+ * https://github.com/LennardKittner/HyperHeadset
+ *
+ * Key differences:
+ * - 62-byte packets instead of 52
+ * - Different base packet structure
+ * - Response uses Report ID 11 (0x0B) instead of 6
+ * - Battery level at response[7]
