Common Header:
  u8 cmdSize   [ 2 = 16, 3 = 64, 4 = 1024 ]
  u8 cmdType

Commands:

*****

Unknown1 (Set_Feature)
  u8 cmdSize = 2
  u8 cmdType = 0xF1
  u8 param1
  u8 param2

{2,F1,02,01} is optionally sent when the group ID is written
{2,F1,02,02} is optionally sent when DPI settings are written
{2,F1,02,04} is optionally sent when LED settings are written
{2,F1,02,08} is optionally sent when the polling rates are written
{2,F1,02,10} is optionally sent when the DPI field is written
this might force the mouse to update certain parts of its state?
