+0x0a USB Polling Rate [0x01-0x04]->[125,250,500,1000]
+0x0c 0x11-0x15 wert für häckchen bei dpi, erstes 0x11 zweites 0x12 usw..
+0x0d-0x16 jeweils 2 byte most significant byte last, * 50 -> annäherung an dpi -50
+
+0x45 -> Lighting Mode, 02 Steady, 01 Colorful Streaming, 03 Breathing
+0x47 -> 0-4 Brightness und 0-4 Speed bei colorful 0x(br)(sp)
+0x48 -> Brightness bei Steady 00-40
+0x4c -> 0-4 Brightness und 0-4 Speed bei steady 0x(br)(sp)
+0x4e-0x63 -> Bei Breathing RGB * 7
+0x67-0x7a -> Bei Steady RGB * 7
+bei einem modus wechsel ändert sich brightness und speed nicht auser man ändert sie nochmal explizit

+Mouse Sensitivity and Improve Pointer Precision does nothing

+0x08-0x0b 4 Byte für linke Maustaste
+0x0c-0x0f 4 Byte für rechte Maustaste
+0x10-0x13 4 Byte für Mausrad taste
+0x14-0x17 4 Byte für taste 13, Zurück Taste, über taste 5,6

+0x1c-0x1f 4 Byte für taste 14, 1. über mausrad
+0x20-0x23 4 Byte für taste 15, 2. über mausrad
+--was machen die 4 Byte die hier leer sind ?--
+0x28-0x47 Jeweils 4 Byte (3 Sicher) für die Belegung der Tasten 1-8 an der Seite
+
+Tastenbelegung
+    Leftclick ->    0x11 0x01 0x00, restliche 2 Byte egal? -> schätze nicht werden mit null geschrieben wenn was anderes drinnen stand
+    Rightclick ->   0x11 0x02 0x00, restliche 2 Byte egal?
+    Forward ->      0x11 0x10 0x00 0x00
