Dequeue Pointer (DQP): 
This field defines the high order bits of the 64-bit address of 
the current Debug Capability Event Ring Dequeue Pointer.  
Software shall initialize this register before setting the Debug Capability Enable field in 
the DCCTRL register to '1'.

Dequeue ERST Segment Index (DESI): 
This field may be used by the xHC to 
accelerate checking the Event Ring full condition. This field is written with the low order 
3 bits of the offset of the ERST entry which defines the Event Ring segment that the 
Event Ring Dequeue Pointer resides in.

Debug Capability Enable (DCE): 
Setting this bit to a 1 enables xHCI USB Debug 
Capability operation. This bit is a 0 if the USB Debug Capability is disabled. Clearing this 
bit releases the Root Hub port assigned to the Debug Capability, and terminates any 
Debug Capability Transfer or Event Ring activity.

Device Address (DADDR): 
This field reports the USB device address assigned to the 
Debug Device during the enumeration process. This field is valid when the DbC Run bit 
is 1.
