URS_HARDWARE_EVENT enumeration (urstypes.h)

  • Article

Defines values for the hardware events that a client driver for a USB dual-role controller can report.

Syntax

typedef enum _URS_HARDWARE_EVENT {
  UrsHardwareEventNone,
  UrsHardwareEventDetach,
  UrsHardwareEventIdGround,
  UrsHardwareEventIdFloat,
  UrsHardwareEventPortTypeDfp,
  UrsHardwareEventPortTypeUfp
} URS_HARDWARE_EVENT, *PURS_HARDWARE_EVENT;

Constants

 
UrsHardwareEventNone
Internal use only.
UrsHardwareEventDetach
A detach event occurred on a port of a USB Type-C system.
UrsHardwareEventIdGround
This event indicates that the ID pin is grounded.
UrsHardwareEventIdFloat
This event indicates that the ID pin is floating.
UrsHardwareEventPortTypeDfp
The Type-C connector has resolved to DFP. Not to be used directly by the URS client driver.
UrsHardwareEventPortTypeUfp
The Type-C connector has resolved to UFP. Not to be used directly by the URS client driver.

Remarks

Values defined for USB Type-C systems should not be directly used by the client driver. Instead the driver should report that it does not support hardware event reporting by calling UrsSetHardwareEventSupport. These hardware events are detected by a USB Type-C connector driver, see USB Type-C connector driver programming reference.
