Blootoothd floods the console

Hi,

I use two bluetooth mices (Microsoft Sculpt Comfort Mouse) on my macs (Macbook Pro mid 2012 und Mac mini late 2012 with High Sierra 10.13.4). Yesterday I noticed some delays when using the mouse. So I look in the console.

Everytime I use the mouse the following entries appear in the console:

08:38:23.880151 +0200 bluetoothd    EVENT:  ModeChange
08:38:23.880220 +0200 bluetoothd == IOBluetoothBroadcomSchedulerWorkaround start
08:38:23.881359 +0200 bluetoothd USBProductID 0x821D USBVendorID 0x5AC
08:38:23.881395 +0200 bluetoothd schedularWorkaroundActive? 0
08:38:23.881431 +0200 bluetoothd active? 0
08:38:23.881465 +0200 bluetoothd == IOBluetoothBroadcomSchedulerWorkaround end

Does anyone know what that is?

I already reset the bluetooth module.

Best regards

Kay
