4.2.1 

USB: VBUS Overcurrent 

This history entry is recorded when an overcurrent is detected in the VBUS. If this history 
entry appears when an USB device is connected, the current drawn from the VBUS by the 
USB device may exceed the supply capacity. 

4.2.2 

USB: LS device 

This history entry is recorded when an LS (Low Speed) device is connected. This history 
entry is not recorded if connected via a USB hub. 

4.2.3 

USB: FS device 

This history entry is recorded when an FS (Full Speed) device is connected. FS devices 
include USB hubs recognized as FS. This history entry is not recorded if connected via a 
USB hub. 

4.2.4
