+SUPERSTRIKE TUNING Feature (0x1B0C)
+-----------------------------------
+This feature controls the HITS (Hall-Effect Inductive Trigger Switch) settings
+for the left and right mouse buttons.
+
+Capabilities (function 0x00):
+  Byte 0: Flags
+  Byte 1: Button count (3, but only 0 and 1 are accessible)
+  Byte 2: Max actuation value (40)
+  Byte 3: Max rapid trigger value (20)
+  Byte 4: Max haptics value (20)
+
+Read button settings (function 0x20, param: button_index):
+  Response: [button_index, actuation, rapid_trigger, haptics, ...]
+  - actuation: 4-40 (quantized to multiples of 4)
+  - rapid_trigger: 1-20 (cannot be set to 0)
+  - haptics: 0-20 (quantized to multiples of 4: 0, 4, 8, 12, 16, 20)
+
+Write button settings (function 0x10):
+  Params: [button_index, actuation, rapid_trigger, haptics]
+
+Solaar Settings:
+  - superstrike-tuning_actuation-{0,1}: Range 1-10 (maps to device 4-40)
+  - superstrike-tuning_rapid-trigger-level-{0,1}: Range 1-5 (maps to device 1-20)
+  - superstrike-tuning_haptics-{0,1}: Range 0-5 (maps to device 0-20)
+
+Note: Feature 0x80E0 (unknown:80E0) appears to be a non-functional stub for haptics.
+Haptics are actually controlled via byte 3 of the SUPERSTRIKE TUNING feature.
+
+Note: Feature 0x9403 (unknown:9403) appears to be a hidden BHOP (bunny hop) feature
+that is not accessible via HID++.
